General Safety Precautions
General Safety Precautions
Particular attention must be paid to the notes and warnings referring to possible faults in the radar display, since such faults can
impair the detection of targets.
The radar can perform its safety function if, and only if, the transmission power and the receiver sensitivity
are adequate. Therefore, these characteristics must be checked regularly (by means of the Performance
Monitor – see Section 21).
Connected position receivers must fulfil the standard IEC 61162-1 1).
ARPA target data are directly dependent upon the accuracy and proper functioning of the selected speed
sensor and the gyro compass.
DANGER: High frequency radiation
Persons must definitely avoid being present in the radiation danger zone
of the rotating antenna.
In the case of work being done on the antenna unit, the antenna switch
situated there must be set to 0 and the transceiver must be disconnected from the ship’s mains.
☞
There is no international agreement about the danger posed by high frequency radiation of the kind
produced by the radar systems. In most countries, a radiation density exceeding 100 W/m2 is considered to be dangerous; in some countries, values over 10 W/m2 are regarded as not being completely
safe.

General Safety Precautions
Operating Instructions
DANGER: Injury caused by a rotating antenna
When the radar system is switched to "ON", it is possible that, instead
of the expected antenna, a different one will begin to rotate. Therefore, it
must be ensured beforehand that all antennas can rotate freely and that
are no persons near the antennas.
The units may be opened only by qualified, trained persons.
DANGER: Dangerous voltage
Even when the equipment is switched off, there can be a dangerous
voltage present at exposed contacts in the units. Therefore, before a unit
is opened, it must be ensured that the voltage supply to the unit is
disconnected from the ship’s mains, and that it remains disconnected.
Because of the capacitors contained in the units, there can be a
dangerous voltage present in any unit even several minutes (or several
hours in the case of monitors) after switching off and disconnection
from the power supply.
☞
If the units are to be disconnected from the ship’s mains, it must be remembered that each antenna
unit, each transceiver electronics unit and each indicator normally has its own supply of power from
the ship’s mains.
If, for the transfer of signals (e.g. transfer of the heading signal from the compass system), synchro
transmitter are used, a dangerous voltage exists in the units until the reference voltage is switched
off.

Operating Instructions
1 Overview
1.1 RADARPILOT ATLAS 1000
Overview
Subjects of this Section:
◆
Brief overview of the parts of the system
◆
Optional parts and functions
The radar system can be configured in two main versions:
the basic version, called RADARPILOT ATLAS 1000
an expanded version, called CHARTRADAR ATLAS 1000 (or MULTIPILOT ATLAS 1000, see
Section 1.3) which, in addition, offers the possibility to display selected parts of the Electronic Chart
on the radar screen in an alternative display mode.
Both versions are approved according to the published radar performance standards.
1.1
RADARPILOT ATLAS 1000
From the components of the RADARPILOT, it is possible to assemble radar sets and radar systems for
all types of ship.
In a RADARPILOT System, the following components can be combined with each other in any desired
manner:
X-Band or S-Band transceiver and antenna
Electronics Units with manual (EPA) or automatic (ARPA) plotting aids.
12" or 16" indicators
Radar indicators as console versions or desk-top versions
The scope ranges from single systems to multiple systems consisting of five transceivers and five indicators.
Not only the system configuration but also the manner of use is extremely flexible: with just a few operating steps, each radar indicator can be switched to act as the master indicator of any desired transceiver
or as a slave for any transceiver that is operating (interswitch function).
☞
On the master indicator, all functions of the radar can be operated, i.e. both on the transmitter side
and on the receiver side. On the slave indicator, most functions on the reception side can be set
independently of the master.
All radar sets are suitable for high speed craft (HSC’s) too (if the antenna gearboxes are chosen appropriately), and on ships with normal speed they can be operated at twice the antenna rotation rate if this
is required by the situation.
1.2
CHARTRADAR ATLAS 1000
The CHARTRADAR consists of the same components as those of the RADARPILOT, and also has all
the characteristics of the RADARPILOT. In addition, it offers the possibility that the vector charts which
exist in the CHARTPILOT can be displayed on the radar. 1)
1)
From the point of view of approval, the CHARTRADAR can be configured at service level in such a way that it fulfils the regulation IEC
60936-1, "Shipborne Radar" or the regulation IEC 60963-3, "Radar with Chart Functions". In the latter case, there are limitations in the
display of the chart - see footnotes on page 30 and page 43.

1 Overview
1.3 MULTIPILOT ATLAS 1000
RADARPILOT / CHARTRADAR
Operating Instructions
The Electronic Charts are vector charts which are provided by a CHARTPILOT ATLAS 93xx via a data
bus connection.
A CHARTPILOT is therefore necessary for operation of the CHARTRADARs, but is also used together
with RADARPILOTs. CHARTPILOT and CHARTRADAR or RADARPILOT exchange a large quantity of
data with each other, especially relating to the navigation sensors, the tracks, and the alarms that are
generated by the ECDIS which is contained in the CHARTPILOT.
1.3
MULTIPILOT ATLAS 1000
The MULTIPILOT ATLAS 1000 has a different Electronics Unit. There, it can be specified at service level
whether the MULTIPILOT is to perform the functions of the CHARTRADAR or those of the CHARTPILOT 1).
In the first case, the MULTIPILOT ATLAS 1000 does not differ from the CHARTRADAR as far as the
operating procedure and the functions are concerned. All statements made about the CHARTRADAR in
these Operating Instructions are also applicable to the MULTIPILOT ATLAS 1000.
In the second case, the MULTIPILOT ATLAS 1000 does not differ from the CHARTPILOT ATLAS 9330
as far as the operating procedure and the functions are concerned - see Operating Instructions ED 3032
G 232.
1.4
The Equipment Components
The radar systems (RADARPILOT and CHARTRADAR) consist of two segments which are connected to
one another via bus systems (CAN Bus) etc. These segments are the radar indicator and the transceiver/
antenna.
The radar indicator is the central operating and display unit. It consists of
the monitor, with a high-resolution 21" colour screen for the 12" radar or a 29" colour screen for the
16" radar,
the trackball, with which all operating inputs can be made,
the radar keyboard, with which operating steps that are frequently used can be carried out particularly conveniently by means of function keys and rotary knobs,
the diskette drive, which permits very easy servicing and makes it possible to save data and to
exchange data with radar systems installed on other ships, and
the display electronics unit, the heart of which consists of a high-performance computer which also
performs the communication with the display electronics units of the other radar sets installed. In
addition, the interface adaptation for navigation sensors having NMEA interfaces takes place here.
On the radar interconnection box, all ship’s cables leading to the radar indicator are connected. If
necessary, special Interface electronics is also accommodated here.
The parts of the radar indicator are usually integrated within a console. However, they can also be
assembled as a desk-top version without integrating the display electronics and the interconnection box.
The display electronics unit is then installed together with the radar interconnection box to form a single
unit.

RADARPILOT / CHARTRADAR
Operating Instructions
1.5 Scope of Applicability of these Operating Instructions
In addition,
slave monitors can be installed, which repeat the display shown by the indicator to which they are
connected.
slave keyboards or slave trackballs can be installed. Each slave keyboard or slave trackball is
assigned to a slave monitor. For each slave keyboard/trackball, there is an electronics unit called a
keyboard switch which, by means of a single operating step, makes it possible to assign the operating functions to a slave keyboard (trackball) / slave monitor pair.
a video buffer is used, if there is more than one slave monitor connected to an indicator.
The RF components are
the transceiver (electronics unit), which contains the X-Band transceiver or the S-Band transceiver
(transceiver version B = bulkhead), and
the antenna (unit), consisting of
the antenna gearbox (X-Band or S-Band) and
the scanner (5 ft X-Band or 8 ft X-Band scanner or 14 ft S-Band scanner).
The transceiver can also be accommodated in the antenna gearbox, so that there is no need for a
separate transceiver electronics unit (transceiver version A = antenna/mast ahead).
In addition, a unit called
the Interface Expander may be present. When there are more than two radar indicators or more
than two transceivers installed, the switch-over between the indicators and transceivers is performed
by the Interswitch installed in the Interface Expander. If additional interfaces or interfaces having a
non-standardised format have to be implemented, the electronics which is additionally installed in the
Interface Expander performs the necessary interfacing and data distribution.
Examples of various equipment configurations are given in the following illustrations.
The TVA 1) signals entered there are the combined reception signals of the transceivers. In the indicators, these signals are used to generate the radar video signal, as well as the trigger signals and
antenna signals.

2.1
Switching the Radar System On and Off
Switching the radar system ON is done by means of one of the ON/OFF switches or
POWER buttons situated on the radar indicators. When this is done, all indicators and
transceivers are switched on. 1) and
After the warm-up phase of the magnetron - 3 minutes for X-Band and 3.5 minutes for S-Band - standby operation is achieved and the radar function can be switched on; see page 47.
☞
☞
The act of switching an indicator on never causes a transceiver to be switched directly into radar
Mode.
If an attempt to switch over to radar operation occurs before stand-by operation is achieved, the indication WARM UP appears instead of the list of transceivers.
Switching the radar system OFF: Switch off all indicators by means of the ON/OFF switch 2). As long
as there is one of the switches in the ON state, all electronics units of the indicators and transceivers
remain switched on and.
Stand-By Operation
The main difference between stand-by operation and radar operation is that, during stand-by operation,
the transceiver is not transmitting and the antenna is not rotating. Therefore, the radar video is absent on
the PPI, and none of the functions that depend on the transceiver can be operated yet.
During stand-by operation, the magnetron is kept at its operational temperature.
1)
2)
If an display electronics unit is exposed to very low temperatures (around -15°C or less), it can happen that its computer does not start up.
The screen of the associated monitor then remains dark, or becomes dark after a short time. In this case, the radar system must remain
switched on for about 30 minutes (in spite of the dark screen) so that the display electronics units will warm up. If the radar system is then
switched off and is switched on again after a waiting time of a few seconds, the computer will start up in the normal way.
If a indicator has a POWER key, that indicator is switched off by prolonged pressing of this key.

2.2
General Remarks about the Operating and Display Elements
On the indicators of the radar system, many screen display fields also act as switching areas or input
fields which can be operated quickly and intuitively by means of the trackball and cursor.
With these few elements, the entire radar system can be operated from the radar indicator with the aid
of its trackball. In addition, the optional radar keyboard contains function keys and rotary knobs for direct
access to some functions that are needed frequently.
☞
The description of the operating procedure in these Operating Instructions normally refers to the
trackball and cursor. In Section 16, the operating procedure using the optional radar keyboard is
summarised.
Trackball and Cursor
☞
If you are already familiar with graphic man-machine interfaces, you might be able to skip this section. Before doing so,
you should have a look at the picture of the trackball beside
this text.
Every operating step begins with the operator moving the cursor
by means of the trackball to a particular place on the screen (to a
text item, a numerical value, a symbol on the PPI or any desired
place on the PPI). The next step is always the pressing of one of
the trackball keys. In the following, this brief pressing of the key is
called clicking. What then happens depends on the key used, the
element on which clicking took place, and the operating situation,
and is the subject of these operating instructions.
MORE key...
for left-handed
for right-handed
people
people
DO key
The cursor has a resting position to which it goes 30 seconds after the last operating process. This
position is situated beside the PPI, below the ACQ TGT area.
If the cursor is situated outside the PPI, it is shaped like a hand or an arrow. Inside the PPI, it is a set of
crosswires.
The trackball has three keys with two different functions:
DO Key
The most important key is the middle (bigger) one. Almost all data areas react to this key, which performs
the functions that are needed the most frequently. In these operating instructions, it is called the "DO
key". In the following, "clicking" always means clicking with the DO key unless stated otherwise.
MORE Keys
The two keys situated above the DO key are called "MORE keys" in these operating instructions. They
have identical functions 1) which are not needed as frequently. Not all elements which can be operated by
means of the DO key react to the MORE key also, and if they do, then always with functions other than
those of the DO key. Furthermore, by pressing of the MORE key, open menus (for menus, see below)
can generally be closed without any results, and inputs can be aborted.
Data Areas
Some data areas are used only to display numerical values, names or stati.
Example: Target data display
In the case of most data areas, the operating procedure for the functions displayed there is likewise
performed by clicking on the data area.
1)
16
There are two "MORE" keys so that both left-handed people and right-handed people can operate them ergonomically. Their functions are
identical.

2 Basic Settings; General Remarks about Operating
2.2 General Remarks about the Operating and Display Elements
Examples:
Two switch Acquisition/Guard Zone 1 on and off, all that you need to do is to click on the AK / GZ1
button 1).
If the transfer of the course is to be synchronised, click on the currently existing heading value. A
numeric keyboard is then displayed. Input the correct value by means of that keyboard.
And so on.
Basically, the following is true:
Coloured data areas indicate the activated state.
In the case of functions which only have an "on" state and an "off" state, the "on" state is indicated by a
coloured background. Example: IR on a grey background means that Interference Rejection is not
switched on; IR on a coloured background means that it is switched on.
Areas that are flashing in colour signify that the corresponding function (e.g. ACQ TGT, ADJUST etc.)
can be executed.
Sensitive and Insensitive Data Areas
Data areas that can be operated can be insensitive in particular operational states, i.e. they cannot be
operated. For example, after clicking on the TUNE area, tuning can be performed on the master indicator,
but not on a unit switched to act as a slave indicator. On the slave indicator, the TUNE area is displayed
as being insensitive.
☞
Insensitive data area can be recognised from their low-contrast lettering or colouring.
Before pressing of the DO or MORE key, sensitive data areas can be recognised from the black
border which indicates the boundary of the sensitive area as soon as the cursor is situated in this
region. Furthermore, the shape of the cursor changes to that of a hand.
Operating Procedure for the Context Menus
Particular data areas react to clicking by presenting a list of further possibilities - the "context menu", as
it is called. If clicking takes place on one of the buttons contained in the context menu, the corresponding
change in the function takes place and the context menu disappears. In some cases, a further menu is
opened. By clicking on the background area, the context menu can be switched off without any change
of function.
☞ 30 seconds after the last operating process, the context menu switches off automatically.
The Function of the Menu Buttons
Clicking on the buttons MENU to BRILL situated at bottom right
opens menus in which basic settings can be made and which
contain other functions that are not needed very often. Most of
these menus contain several levels, i.e. from the menu that has
been called up, a submenu can be called up, and so on. The higher
levels are listed in the menu header. There, you can return to the
higher level by clicking. Clicking on the highest level or on the
menu button having the same name closes the menu.

Special Features of the Lists of the System Maintenance Manager
The System Maintenance Manager, a subroutine which was created
for maintenance purposes and which the operator too needs from
time to time (see page 133), uses a different form of list which is
similar to that of other operating systems. Important special features
are:
Catalogs and files of the various levels are contained in one and the
same display.
Catalogs are designated by the symbol
or
, and files by the
symbol

How to Brighten a Very Dark Screen
If the screen is set very dark in a very bright environment, it might no longer be possible to recognise

2.4 Degaussing
Degaussing
This section is relevant only for monitors with cathode ray tubes, and not for monitors with flat screens.
As a result of changes in the magnetic field at the location of the monitor, the shadow mask of the
cathode ray tube might become magnetised, which leads to discolouration over the entire screen or in
parts of the display. Because, in the earth’s magnetic field, the ship itself acts as a magnet, such changes
in the magnetic field can also be caused by changes in the ship’s course. The demagnetisation which
then has to be performed on the shadow mask ("degaussing") can be performed manually.
☞
If this does not lead to success, the trouble might also be due to magnetic components or magnetised housings, which must then be removed from the environment of the monitor or degaussed.
Manual Degaussing

Manual degaussing is performed by pressing of the

Operating Instructions
Activating/Deactivating of Slave Keyboards/Trackballs
When a slave monitor is installed together with a trackball and (possibly) a keyboard, this combination
can perform the same functions as the radar indicator to which these units are connected.
☞
If there are "radar indicators" on the bridge wings, they are often slave monitors and slave
keyboards/trackballs.
If there are one or more slave keyboards or slave trackballs connected to an indicator, only one of them
is active at a time; operating procedures can be performed only on the one that is active.
Activating a Keyboard or Trackball
A non-active keyboard or trackball is activated by pressing the DO key for three seconds.
☞
The keyboard/trackball that had been active up until then is thus deactivated. The associated monitor
acts as a slave monitor.
If there is a keyboard present, activation can also be performed by pressing one of the keys RADAR
MODE, CHART MODE or CONN MODE for three seconds. In this case, when the activation occurs, the
switch-over assigned to the key is also performed, see Section 16.

Screen Stabilisation of the PPI: True Motion, Relative Motion
As far as the screen stabilisation of the PPI is concerned, there is a choice between the following:
True Motion (TM): The radar video is fixed; the own ship symbol moves across the screen. The PPI
orientation is North-Up or Course-Up. Either manually, or automatically by means of a TM Reset,
the own ship symbol on the PPI is reset in good time before the PPI boundary is reached; this resetting is done in such a way that the larger part of the PPI lies ahead of own ship.
Relative Motion (RM): Own ship’s position is fixed; the radar video moves relative to own ship in accordance with the movement of own ship. As far as the PPI orientation is concerned, it is possible to
choose between Head-Up, North-Up and Course-Up.
Switching Over between TM and RM
Clicking on the PPI stabilisation area causes a switch-over between
TM and RM.
☞
If the PPI orientation setting is Head-Up, then when switch-over
to TM mode takes place there is automatic selection of North-Up
and setting of the display of trails to "true". In TM mode, relative
trails cannot be displayed.
TM

A TM reset is performed by clicking of the TM RESET area.
☞
The TM RESET area appears, instead of the CENTER area,

the vessel in the "vector time", as it is called. The vector time can be
adjusted.
☞
Past position plot:
In the case of the ARPA radar, past position plots can be displayed
for the targets. The settings for these plots are made jointly with
those of own ship’s past position plot. They have four time markers
at the most, which are set simultaneously on all past position plots.
All vectors and past position plots can be displayed jointly either relative
to own ship (R = relative display) or over ground or through the water (T
= true display).

plotted
Past position plot

Target symbol

Speed vector
Target being

In the case of the relative display, the vector and the past position
plot of own ship are non-existent by definition.
Furthermore, the radar target symbols are supplemented by symbols of
the manual plotting aid or of the automatic target tracking function (see
page 67).
The computation of the vectors is always based on the BT/WT setting
which is displayed for the selected speed sensor.
1)
Speed vector
In the case of the manual plotting aid (EPA radar), the vector is
computed from the last two (manual) plots. Therefore, particular
care is required when plotting on the EPA radar: if the target
being plotted changes its course or speed between two plots,
the vector displayed does not correspond to the actual vector.
In the case of the EPA radar, the last four plots are joined up by a
line. Thus, these markers - in contrast to the time markers of the
ARPA radar - are not at constant time-intervals apart from each
other, i.e. they also have no relation to each other.

Trails
In the true display, trails make it possible for you to reach a conclusion quickly about the manoeuvre
performed by targets. In the relative display, the trails provide a quick overview of the danger situation (a
constant bearing). However, only qualitative information can be obtained from them.
For
radar echoes moving on the PPI, trails can be displayed. These trails can be varied as follows:
The display of these trails can be switched on and off.
Their length can be specified.
If the screen stabilisation of the PPI is set to RM, the trails can be displayed with the PPI orientation
"North-Up" and "Course-Up" relative to own ship or with true (absolute) orientation, i.e. in relation
to the sea bottom 1).
The trails can be deleted so that they have to build up again.

Important Differences between the CHARTRADAR and the CHARTPILOT
Additionally present on the CHARTRADAR:
The Electronic Chart and the radar video are displayed simultaneously in the PPI.
The areas of the Electronics Charts can be replaced by their contours (so that the radar video stands

Not present on the CHARTRADAR:
Only vector charts (i.e. no raster charts, e.g. ARCS charts) and User Chart Objects can be displayed.
The info system (detailed information about the individual chart objects) exists only on the CHARTPILOT. This also contains the information about the date and number of the last ENC update.
The depth contours (Safety Contour, Shallow Contour and Deep Contour, Safety Depth) are set on
the CHARTPILOT and are taken over for the display on the CHARTRADAR.

Adjusting the Chart or Map to the Radar Video
If the majority of the symbols of the Electronic Chart are displaced relative to their radar echoes of these
targets, it can be assumed that the position transferred from the selected position sensor is incorrect. 1)
If no position data having greater accuracy are available, then the Electronic Chart together with the User
Chart Objects and the map can be shifted in such a way that symbols and the associated echoes coincide. This correction is described on page 62.

Rotation of the entire video relative to the map indicates that the heading value is incorrect. The
cause of this might be a faulty compass, or else non-synchronous transfer of the course (for synchronisation of the course transfer, see page 57). However, errors of this kind also occur also if the
compass does not perform a speed error correction or no dynamic correction; these faults should
then be corrected in the compass system, if possible.
If symbols of the User Chart objects or the symbols of the map are displaced relative to their radar echoes of these targets, it must be
considered whether the positions of these symbols have been entered incorrectly.

Radar Function On/Off, Interswitch Functions, Master/Slave Switch-Over
On any radar indicator, any transceiver of the system can be switched to act as the master. On the
master indicator, the radar is operated completely, i.e. both the transmitter side and the receiver side.
Any radar indicator can also be switched to act as a slave of any transceiver that is operating. On the
slave indicator, most of the functions on the reception side can be set independently of the master 1).
Switch-On of Radar Operation
DANGER:
At the instant of switch-on of the radar function, the antenna begins to
rotate and the emission of high frequency radiation 2) is started. In the
case of multiple installations, it can also happen that, instead of the
expected antenna, a different one begins to rotate. Therefore, it must be
ensured beforehand that the antennas can rotate freely and that there is
nobody present close to the antenna turning circles.
The radar transceiver selected last is switched to radar operation by
clicking into the transceiver area and then clicking on the transceiver
designation that is displayed.

USEFUL INFORMATION
Danger Posed by High Frequency Radiation
There is no international agreement about the danger posed by high frequency radiation of the kind
produced by the radar antenna. In most countries, a radiation density exceeding 100 W/m2 is considered
to be dangerous; in some countries, values over 10 W/m2 are regarded as not being completely safe.
The distances from the various antennas at which the radiation density is 100 W/m2 and 10 W/m2 are
stated on page 3.

The rotation of the antenna is monitored. If, because of a defect or the use of the antenna safety
switch, the antenna stops rotating, the transceiver is automatically switched off.

The code of Racons consists of a radially arranged dash-dot code which begins in the radar video a short

Most Racons transmit in the X-Band, but there are some Racons installed which transmit in the S-Band.
The majority of Racons change their transmission frequency slowly throughout the entire frequency band,
and so they are not received in every revolution of the antenna.
For the setting of the radar, the same basic principles are applicable as for SART detection.

ANNEX
OPERATION OF MARINE RADAR FOR SART DETECTION
WARNING: A SART will only respond to an X-Band (3 cm) radar. It will not be seen on
an S-Band (10 cm) radar.
Introduction
l.
A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm)
radar within a range of approximately 8 n.miles. Each radar pulse received causes it to
transmit a response which is swept repetitively across the complete radar frequency band.
When interrogated, it first sweeps rapidly (0.4 µsec) through the band before beginning a
relatively slow sweep (7.5 µsec) through the band back to the starting frequency. This
process is repeated for a total of twelve complete cycles. At some point in each sweep, the
SART frequency will match that of the interrogating radar and be within the pass band of
the radar receiver. If the SART is within range, the frequency match during each of the 12
slow sweeps will produce a response on the radar display, thus a line of 12 dots equally
spaced by about 0.64 n.miles will be shown.
2. When the range to the SART is reduced to about 1 n.mile, the radar display may show
also the 12 responses generated during the fast sweeps. These additional dot responses,
which also are equally spaced by 0.64 n.miles, will be interspersed with the original line
of 12 dots. They will appear slightly weaker and smaller than the original dots.
Radar Range Scale
3. When looking for a SART it is preferable to use either the 6 or 12 n.mile range scale.
This is because the total displayed length of the SART response of 12 (or 24) dots may
extend approximately 9.5 n.miles beyond the position of the SART and it is necessary to
see a number of response dots to distinguish the SART from other responses.
SART Range Errors
4. When responses from only the 12 low frequency sweeps are visible (when the SART
is at a range greater than about 1 n.mile), the position at which the first dot is displayed
may be as much as 0.64 n.mile beyond the true position of the SART. When the range
closes so that the fast sweep responses are seen also, the first of these will be no more than
150 metres beyond the true position.
Radar Bandwidth
5. This is normally matched to the radar pulse length and is usually switched with the
range scale and the associated pulse length. Narrow bandwidths of 3-5 MHz are used with
long pulses on long range scales and wide bandwidths of 10-25 MHz with short pulses on
short ranges.
6. A radar bandwidth of less than 5 MHz will attenuate the SART signal slightly, so it
is preferable to use a medium bandwidth to ensure optimum detection of the SART. The
Radar Operating Manual should be consulted about the particular radar parameters and
bandwidth selection.
Note about item 6: The bandwidth of the radar is not less than 5 MHz. Therefore, the setting described here is not necessary.

4.7 Suppression of the Synthetics and Video
Radar Side Lobes
7. As the SART is approached, side lobes from the radar antenna may show the SART
responses as a series of arcs or concentric rings. These can be removed by the use of the
anti-clutter sea control although it may be operationally useful to observe the side lobes as
they may be easier to detect in clutter conditions and also they will confirm that the SART
is near to own ship.
Detuning the Radar
8. To increase the visibility of the SART in clutter conditions, the radar may be detuned
to reduce the clutter without reducing the SART response. Radars with automatic
frequency control may not permit manual detune of the equipment. Care should be taken
in operating the radar in the detuned condition as other wanted navigational and anti-collision information may be removed. The tuning should be returned to normal operation as
soon as possible.
Gain
9. For maximum range SART detection the normal gain setting for long range detection
should be used i.e., with a light background noise speckle visible.
Anti-Clutter Sea Control
10. For optimum range SART detection this control should be set to the minimum. Care
should be exercised as wanted targets in sea clutter may be obscured. Note also that in
clutter conditions the first few dots of the SART response may not be detectable, irrespective of the setting of the anti-clutter sea control. In this case, the position of the SART may
be estimated by measuring 9.5 n.miles from the furthest dot back towards own ship.
11. Some sets have automatic/manual anti-clutter sea control facilities. Because the way
in which the automatic sea control functions may vary from one radar manufacturer to
another, the operator is advised to use manual control initially until the SART has been
detected. The effect of the auto sea control on the SART response can then be compared
with manual control.
Anti-Clutter Rain Control
12. This should be used normally (i.e. to break up areas of rain) when trying to detect a
SART response which, being a series of dots, is not affected by the action of the anticlutter rain circuitry. Note that Racon responses, which are often in the form of a long
flash, will be affected by the use of this control.
13. Some sets have automatic/manual anti-clutter rain control facilities. Because the way
in which the automatic rain control functions may vary from one radar manufacturer to
another, the operator is advised to use manual control initially until the SART has been
detected. The effect of the auto rain control on the SART response can then be compared
with manual control.
Note:
The automatic rain and sea clutter controls may be combined in a single ’auto-clutter’
control, in which case the operator is advised to use the manual controls initially until the
SART has been detected, before assessing the effect of auto.

CAUTION:
The right choice of navigation sensors, the right setting of the navigation
data and a continuous overview of the status of the selected navigation
sensors are very important for safe navigation.
In the case of multiple installations, the settings described in the following only have to be made on one
of the radar indicators. All components of the system are automatically supplied with the navigation data
resulting from the settings made on any desired radar indicator. This also applies to the CHARTPILOT,
if there is one.
5.1
Compass
For the transfer of the heading information, a technique is often used which transfers heading changes
only, and not the absolute value. Therefore, in such cases, after switch-on of the radar system and after
failure of the signal transfer, the synchronism of the heading transfer process must be checked and, if
necessary, corrected.
Display of the Heading Value Used
The heading value currently being transferred from the
compass and used in the entire radar system is displayed in
the HDG area.

5.2
Speed Sensor
There may be several speed sensors connected to the radar system. One of them has to be chosen. In
the case of speed sensors which transfer the longitudinal speed only, the drift and set can be entered
manually. As an alternative to selection of a speed sensor, it is also possible to input the speed manually,
if necessary. If fixed radar-targets are available, the speed can be determined by Reference Target
Tracking.
☞
The speed sensors also include position sensors which transfer not only the position but also the
speed and course made good. Compared to the present-day state of the art, they generally do not
meet the IMO Performance Standards for SDME (Speed and Distance Measuring Equipment).
Therefore, they might not be configured in the system, and so it might not be possible to select them
for speed input.

status, and the selected sensor.

5.3 Position Sensor
5.3
Position Sensor
There are often several position sensors connected to the system. One of them has to be selected. As
an alternative to selecting a position sensor, it can - if necessary - also be specified that the system position is to be determined on the radar by dead reckoning (EP = Estimated Position) using the gyro heading
and the speed data of the selected speed sensor.
After the position sensor has been selected, the accuracy of the position data must be checked continuously. Constant errors in the transferred position can be compensated manually.
General Remarks about Position Data
On the radar, it is basically necessary to distinguish between the following positions:
1.
System position: The display is shown in the position display when the cursor is situated outside
the PPI. "System position" is normally defined as a position in the forward part of the ship - usually
the location of the transducer of the DOLOG or of another installed log.
2.
Reference position for bearings: All displays relating to own position (own ship symbol, VRM/EBL,
range/bearing of the cursor position, CPA/TCPA) refer to the antenna position of the radar that is
being operated. This is made clear in the Position Display by the entry REF RADAR.
☞
3.
There is no LAT/LON display of this position, but in the small display-ranges the LAT/LON
values can be read off as the cursor position if the cursor is moved to the radar origin.
Cursor position: The display is shown in the position display when the cursor is situated within the
PPI. This display indicates the absolute geographical position.
All LAT/LON values are based on the geodetic datum "WGS 84".
☞
Important: Only position receivers may be connected to the radar system that output the position
values in the geographical reference system WGS 84 via an interface as per IEC 61162-1 1).
Display of the Position Data Used
In the Position Display, the position data used in the system
are displayed:
Behind POS: the selected position sensor.
Behind LAT and LON: the system position.
Behind COG and SOG: the values of course and speed
over ground that are transferred from the selected speed
sensor.
Behind ADJUST: the value of the manual position-correction in metres N/S and W/E,

Using Dead Reckoning to Determine the Position
If there is no position sensor available, or if the data from the position sensor are invalid or faulty, the
only remaining possibility of determining the position is the dead reckoning method, using the gyro
heading, the data from the selected speed sensor, and the drift value if such a value is entered.
WARNING:
The accuracy of the dead-reckoned position (display: EP) must be
checked continually. For safety reasons, an available position-sensor
must be selected as soon as possible.
The dead reckoning process is switched on in the same way as the selecting of a position sensor - see
above. During this process, the "position sensor" EP (= Estimated Position) must be selected. The special
feature is that, if EP is preselected, the starting position displayed in the Multidisplay can be changed.
The dead reckoning process begins with this position after pressing of the SELECT button.

5.3 Position Sensor
Check of the Accuracy of the Position Data
In the PPI, any inaccuracy in the position data causes displacement between
the own ship symbol and the radar video on the one hand, and
the tracks and the maps on the other hand.
The position used by the radar is normally accurate enough if the symbols of a map that may have been
generated for this purpose coincide with the videos of the radar targets when the display range is set to
a small value.
Correction of a Constant Position-Error (Position Offset)
If the displayed position is incorrect, the videos of fixed point-targets (e.g. buoys) do not coincide with the
symbols of these targets that are entered at the correct positions in a map. The position error is corrected
manually by making the video of a fixed target coincide with its map symbol:
1.
Switch on a sufficiently small radar range.
2.
Click on the ADJUST button. By flashing, the button indicates that the cursor in the PPI now has a special function.

The entire track and map synthetics move by an amount equal to the position offset. The position offset that is entered continues to be displayed behind ADJUST. 1)
In this way, each direction can be corrected by up to 999 m.
1)
Check that the other symbols of the map too now coincide as well as possible with their radar
echoes. If necessary, processes 2 to 4 can be repeated on the basis of the position offset that exists
at that time.
☞
If the entire video has a rotational displacement relative to the map, this indicates that there is
probably a compass error. Either the synchronisation with the compass system is inadequate
(this must then be corrected – see page 57) or the compass system itself has a static or
dynamic course error. This should, if possible, be corrected in the compass system.
Deleting the Position Offset
The position offset is deleted automatically as soon as a
different position-sensor is selected.
The position offset is deleted manually by clicking on the

USEFUL INFORMATIONS
Latitude-Dependent Errors in the Display of the EBL
With the type of projection used for the longitude/latitude grid in the radar, the parallels of latitude become
more strongly curved with increasing latitude, while the meridians converge increasingly with increasing
distance from the equator (i.e. the direction of a meridian at the edge of the PPI is not 0° - 180° but might
be 358° - 182°); in other words, their directions no longer correspond to the degree scale at the edge of
the PPI.
In contrast to this, the EBL is always displayed as a straight line; its bearing displayed as an EBL value
has an error.
The following table shows the maximum errors for the various latitudes and range settings.

7.2
Operating Instructions
Procedure of the Target Acquisition
The ARPA radar permits manual and automatic acquisition of up to 50 targets. For automatic target
acquisition, there are two combined acquisition and surveillance zones 1) available. Acquired targets are
tracked automatically.
In the case of manual target acquisition, the target video is marked manually, and is thus initially
provided with the dotted square
. The radar then checks during the next three revolutions of the
antenna to determine whether the echo occurs twice at this position. If it does, this target is tracked automatically by the radar. If it does not, the radar does not recognise any target at this position, and the
LOST TGT alarm occurs. The target just acquired but lost is marked with the flashing symbol
In the case of automatic target acquisition, the radar evaluates all radar echoes appearing in the acquisition/guard zones. If the echo appears at a certain position at least six times during ten revolutions of
the antenna, it is evaluated as a radar target.
If the echoes do not belong to a target already being tracked, the position is treated as an acquired target
and is marked with the flashing symbol
. The alarm TARGET IN AZ appears, or - if the target was
already being tracked when it entered the acquisition/guard zone - the alarm TARGET IN GZ appears.
After acknowledgement of the alarm, the automatic target tracking begins.
☞ Automatic target acquisition is switched on and off together with the display of the acquisition/guard
zone - see page 69.
☞ If there are already 50 targets being tracked and another target is then acquired, the AZ OVERFLOW alarm appears. In this case, at least one non-critical target must first be deleted.
When the automatic tracking begins, the radar determines the movement of the target.
If the absolute speed determined for the target is less than 1.5 κν, the target is classed as a fixed
target; the symbol
appears.
If the speed of the target exceeds 1.5 kt, it is classed as a moving target and is marked with the
symbol
If the functions are switched on, also the speed vector is now displayed, the computation of collision
risks is performed continuously, and the past position plot is built up.
The target is now tracked automatically until
it is deleted manually or
it is lost because, during five revolutions of the antenna, no correlation of the video can be found by
the radar, or the detection probability falls below 50%, or
it leaves the target tracking range of 20 NM.
If a target is lost, a LOST TGT alarm appears and the lost target is marked accordingly.
☞
☞
The number of targets being tracked should be kept as small as possible; the presence of too many
targets causes confusion on the screen and distracts the operator’s attention from what is really
important.
Targets that are no longer relevant should be deleted in order to minimise the number of LOST TGT
alarms caused by targets leaving the radar range.
In the case of tracked targets entering a clutter area (rain or sea clutter), a "target swap" might occur;
parts of the rain front are suddenly being "tracked". A target swap can also occur if there are targets
situated close together or close to land. In the case of target swaps, no warning is given.
WARNING:
Automatic target acquisition and tracking are ensured only if the radar
video is OK, i.e. if it is adjusted in the same way as would also be necessary for visual evaluation.

Selecting the Reference Targets for Reference Target Tracking
If at least one fixed target 1) is selected as a reference target, the radar can determine own ship’s speed
vector with the aid of this target’s relative motion. By means of this "reference target tracking", the radar
also acts as a speed sensor, and can be called up as such under REFERENCE TARGET SPEED.
Selecting a reference target: Click on the fixed target with the
MORE key, and then click on SELECT REFERENCE TARGET (with
the DO key).

Differences between the EPA radar and the ARPA radar
The EPA radar differs from the ARPA radar principally in the fact that, on the EPA radar, targets have to
be acquired manually and can only be plotted semi-automatically. Furthermore, on the EPA radar, no
targets can be defined as references for reference target tracking.
8.1
Manual Target Acquisition and Semi-Automatic Plotting
On the EPA radar, up to 50 targets can be acquired manually and tracked semi-automatically.
In the case of manual target acquisition, the presumed target video is marked, and as a result it is
initially provided with the dotted square
For semi-automatic target tracking, the same target is marked manually with the second plot several
minutes later at its new position. The radar now computes the speed vector of the target and displays
that vector (if this function is selected - see page 34). The first plot is now displayed as the past position
plot. The target symbol 1) changes. It moves along with the target on the computed course at the
computed speed.
The plotting must be repeated if the target symbol does not coincide with the target video, but not later
than within 15 minutes. After 10 minutes in each case, the operator is reminded by the PLOT xx NO
UPDATE alarm that a new plot should be set. If the next plot is not then performed within five minutes,
the plot is aborted and the alarm PLOT XX ABORTED appears.

10.1
General
Trial manoeuvres are needed mainly for collision avoidance. In this process, a planned manoeuvre of
own ship is simulated and the effect of this manoeuvre on the targets being tracked is checked in a
graphic display.
The
trial manoeuvre can be specified by
simulation of a course change, including the radius to be used by the ship and
the period of time up until the beginning of the simulated manoeuvre (the delay) and by
simulation of a speed change at the instant of the manoeuvre.
There are two display-modes available:
At the instant when the trial manoeuvre function is switched on, a switch-over to relative display
mode takes place. This display mode is used for fast setting of the necessary course-change, of the
delay and of the speed change.
In true display mode, the manoeuvre radius that can then be set and the acceleration 1) for the set
speed-changes are taken into account additionally.

recognised from the fact that the vector of a target is pointing towards the own ship symbol (constant
bearing). A manoeuvre must be simulated which avoids this constant bearing while at the same time
fulfilling other conditions (e.g. keeping within the channel, avoiding shallow water, etc.).
A suitable vector-length should be set.

Editing of Pre-planned Tracks
Subjects of this Section:
◆
Editing and modification of tracks
◆
Management of tracks
Before a Pre-planned Track can be displayed and used in the PPI, it must be edited on a CHARTPILOT
or on a radar indicator. If there is a CHARTPILOT, it can and should be used for this work.
☞
On the CHARTPILOT, e.g. on the basis of the Electronic Chart, tracks can be edited much more
conveniently and also - thanks to the test possibilities available there - with greater nautical safety.
Pre-planned Tracks are accommodated in catalogs, and can be identified within the catalog by means
of a track number and a track name. Catalogs can be created and also - if necessary - deleted. Tracks
can be generated (edited), and existing tracks can have their contents altered, or can be assigned to
other catalogs, or can be deleted.
☞
☞
If there is a CHARTPILOT, it must always be in the switched-on state when work on tracks is being
done on the radar indicator, since the track data are physically stored in the CHARTPILOT.
If there is no CHARTPILOT in the system and if the tracks are to be used on several radar indicators,
the tracks - including the catalogs - must be transferred to the other radar indicators; see page 143.
The menus that are needed in connection with the editing of the tracks are opened from the TRACK
menu which is opened by clicking on the TRACK button.

RADARPILOT / CHARTRADAR
Operating Instructions
11.1 Generating a New Pre-planned Track
Position of the waypoint. Geographical position based on WGS 84.
Curve radius. Radius of the curve along which the ship is to sail at the waypoint
Sailing Mode. This specifies whether a track section longer than 20 NM from this waypoint to the
next one is to be displayed as a rhumb line (Sailing Mode = RHUMB LINE) or as a great circle
(Sailing Mode = GREAT CIRCLE) 1).
Track Control Mode. (TO WAYPOINT or TO TRACK). In the system configuration involved here,
this parameter is not important.
General Editor Characteristics
The position of the waypoints can be defined graphically or by alphanumeric input (both when a new
waypoint is being inserted and when the waypoint position is being changed).
When a new waypoint is being inserted, the curve radius, Sailing Mode and waypoint name are taken
over from the preceding waypoint and are also entered for the inserted waypoint.
Selecting the editing function is done by clicking on the
editing function button by means of the MORE key and
then clicking on the desired function by means of the DO
key.
The editing function is activated by clicking on the
editing function button. This is also in the active state
immediately after an editing function has been selected.
The fact that the editing function is active is indicated by
the fact that the editing function button is flashing.
The active editing function is deactivated by clicking on
the (flashing) editing function button or by clicking into the
PPI by means of the MORE key.

For graphic editing, at least the display of the legs and of the waypoint symbols must be in the
switched-on state - see page 38.
Entering of Waypoint Data
The sequence in which editing is performed is partly a matter of personal preference and partly
dependent on the circumstances. For example, all waypoints can first be inserted graphically; then, in the
second step, the position is set alphanumerically to the precise value if necessary. (This procedure is
described in the following.)
WARNING:
Naturally, the inserting and moving of the waypoints can also be
performed generally by means of alphanumerical inputs. If a track lying
outside the radar range is to be edited while the ship is sailing, the
graphical methods are usually not appropriate.
1)
Great circle approximation: If the Sailing Mode GREAT CIRCLE has been entered at a waypoint on the Pre-planned Track and the
distance from the next waypoint is larger than 20 NM, this track section is automatically approximated to a great circle. For this purpose,
the program divides this track section into subsections, each having a length of 10 NM, and places the ends of these subsections on the
great circle.

If the waypoints have been positioned so unfavourably (short
distance between waypoints, acute angles) and/or the radii
have been chosen so large that the ship will probably not be
able to sail along the track, this situation is indicated by means
of a special display of the track:
The tracklines (the straight lines up to the last waypoint
and up to the currently valid waypoint) are extended as far
as the waypoints.
In the display, the circular arc defined by the radius is
moved along the trackline to the last waypoint until it fits
between the two tracklines.
This movement takes place up to the last waypoint at the
most, but not further than up to a distance of 20 NM
between the beginning of the curve and the waypoint.
Behind the curve end of waypoint 7, this
curve does not fit into the angle formed by
waypoints 7, 8 and 9. Therefore, the
curve is shown displaced, and the display
of the Programmed Track is interrupted
by the display of the tracklines.

Whether radar targets can be detected up to this theoretical range, even with optimum video setting,
depends not only on the atmospheric conditions but also on the characteristics of the target:
Large targets with good reflection characteristics produce strong echo signals and are displayed with
corresponding clarity on the screen.
Smaller targets situated in the shadow of large objects are not illuminated by the radar pulses and
are therefore not displayed.
Flat coasts have an unfavourable reflection cross-section and cannot be recognized until they have
been approached more closely. On the other hand, high coastlines and mountainous regions further
inland are recognised at a very early stage.
In the coastal approaches, the tide rip lines and surf areas are displayed similarly to coastlines.
However, this rather irritating display can be a valuable orientation aid for the coastal navigator.

15.2 Distortions of the Radar Video
RADARPILOT / CHARTRADAR
Operating Instructions
The reflections of radar waves from ice depend largely on the surface structure of the areas illuminated by the radar. Rough and jagged surfaces produce good echo displays, whereas smoothly
frozen-over surfaces, rounded surfaces and surfaces at an oblique angle generally reflect the transmitted pulses away from the ship. Thus, for example, the echo display of large icebergs can fluctuate
extremely severely, depending on the existing aspect.
The detection of low-lying blocks of ice (growlers) probably presents the greatest uncertainty:
WARNING:
Even if the anticlutter facilities are operated carefully, the echoes from
growlers can no longer be definitely identified if moderate disturbances
from the sea surface are present.
15.2
Distortions of the Radar Video
Because of the physical characteristics of the radar principle used, the video displayed does not correspond exactly to the position and form of the reflecting target. A distinction must be drawn between radial
distortions (in the direction of the target) and azimuthal distortions (perpendicular to the target direction)
- see figure on next page.
Radial Distortions
Radial distortions in the direction of transmission are caused by the fact that a target reflects the transmitted pulse for as long as the pulse is moving past the target 1). Thus, radial lengthening depending on
the pulse duration occurs on the screen. In the case of range measurements, it must be noted that the
echo edge facing own ship corresponds to the true front edge of the target.
If there are several targets behind one another with small (radial) distances between them, they are
shown separately on the screen if, and only if, their distance apart is so large that the radial lengthened
echoes do not overlap.
Azimuthal Distortions
Azimuthal distortions are caused by the width of the beam radiated by the antenna. A point target
appears wider the further away it is. At a distance of 10 NM with a horizontal antenna-beamwidth of 1.5°,
an individual target is displayed as an arc with a length of 480 m. Because of this effect, individual targets
situated beside one another can merge to form a single target.
Not only individual targets but also small spits of land aligned in the radial direction appear wider than
they really are, and radially oriented entrances appear narrower than in reality.
☞
As a result of azimuthal distortions and/or changes in the target position, the radar centroid of a
target can change, especially at short range. In the case of a target being tracked, this can lead to
a sudden change in the displayed vector.
In addition to these undesirable azimuthal distortions, targets can also be deliberately widened with
increasing distance, so that narrow, close-range targets too can be seen clearly. This function is used in
the Clean Sweep Modes MEDIUM and OPEN SEA. It ensures that the azimuthal distortion corresponds
to the radial distortion over a wide range of distances. Because the radial distortion depends on the pulse
length, when Target Enhancement is switched on the targets are displayed particularly large by the selection of Long Pulse.
1)
The pulse length setting LP thus generates larger radial distortions than SP.

Undesirable Echo Displays and Effects
Disturbances of the radar video are caused by
meteorological processes,
reflections from the sea surface,
radar signals from other transmitters,
false echo displays,
sectors of reduced radar visibility,
superrefraction and subrefraction.
Influences of Meteorological Processes
The influence of meteorological phenomena such as fog, rain, snow or hail on the radar video increases
with the size of the droplets in relation to the radar wavelength, and with the density of the droplets. The
shorter-wave X-band radar (with a wavelength of 3 cm) is therefore generally impaired more severely by
meteorological influences than is the longer-wave S-band radar (10 cm wavelength).
X-Band Radar
Even in the X-band radar, fog causes practically no disturbances, whereas precipitations with larger droplets attenuate the transmitted radar pulses and thus weaken to a greater or lesser extent the display of
targets situated behind extensive areas of precipitation. Furthermore, throughout their entire extent, rain,
snow and hail reflect part of the transmitted energy and produce echoes in the form of milky areas in the
radar video (backscatter).
Because of the very different signal structures of useful targets and rain areas, rain clutter can be noticeably reduced by the rain clutter suppression function.

15.3 Undesirable Echo Displays and Effects
RADARPILOT / CHARTRADAR
Operating Instructions
In the case of strong, extended areas of rain, the losses become so great that the achievable range is
reduced very severely. Useful targets might be completely concealed.
S-Band Radar
The S-band radar „sees“ through the rain with practically no attenuation losses, and even detects targets
in and behind a rain area. The echo signals caused by the rain are only displayed weakly. Similar behaviour is exhibited in the case of hail and snow.
In this case too, unusually heavy rain can reduce the achievable ranges and thus cause sudden loss of
targets.
Reflections from the Sea Surface
Clutter echoes from the surface of the sea can be recognised from the fact that a mostly circular but
eccentric area displaced in the wind direction and having non-uniform brightness is formed around the
own ship symbol (sea clutter). These echoes make targets in this region more difficult to detect and track,
but they have no effect on the display of targets situated behind the reflection zone.
These disturbances are more severe in the case of a radar antenna mounted high up than for one
mounted lower down. The area covered by these disturbances increases with increasing sea state, and
is increased particularly by steeper waves.
With the aid of the sea clutter suppression function, the disturbance echoes described above can be
reduced. However, since this also weakens the display of targets and because the target might not be
displayed with every revolution of the antenna, maximum concentration by the observer is necessary. In
the case of automatic target tracking, the sea clutter suppression function can lead to the loss of targets
due to the attenuation of the signals.
Disturbances Caused by Other Radars
Transmissions from other radars working in the same electrical frequency band occur as disturbances in
the form of small points or dashes. These move in rapid succession along straight or curved tracks to the
centre of the screen or in the opposite direction.
These disturbances appear particularly clearly at the larger range settings, but they impede radar observation to an insignificant extent only. They can be almost completely eliminated by means of the Interference rejection function.
False or Indirect Echo Displays
False or indirect echo displays ("ghost echoes") occur as a result of reflection of the radar pulses by the
ship's own superstructures of all kinds and by nearby objects that reflect very well. Therefore, a typical
feature of these echoes is that they appear at the bearing of the reflecting surface, regardless of the real
position of the targets.
When two ships pass one another on parallel courses, multiple echoes can often be observed as a result
of pulses reflected to and from several times between the ships' sides. On the screen, a series of equispaced echo displays of decreasing intensity appears at the bearing of the object.
Sectors of Reduced Radar Visibility
Sectors of reduced radar visibility occur as a result of own ship's superstructures which impair and
prevent rectilinear propagation of the radar pulses. Theoretical determination of the geometry of these
sectors and of their influence on the display of targets is possible to an inadequate extent only. An effective practical method consists of determining the shadow sectors against the background of disturbance
signals from the sea surface (sea clutter).

15.4 Sector Blanking
Superrefraction - Subrefraction
If the normal refraction gradient for the radar wave in the maritime boundary layer of the atmosphere is
changed by external influences, subrefraction occurs when the transmitted beam is bent upwards away
from the earth’s surface, and superrefraction occurs when the transmitted beam is bent down towards the
earth’s surface.
In the case of superrefraction, false echoes of targets outside the set range of measurement can occur:
the echo of a transmitted pulse is not received and displayed until the occurrence of the CRT deflection
trace controlled by the next transmitted pulse or by the one after that. The resulting ghost echoes can
occur at any position. Since the position of ghost echoes depends on the pulse repetition frequency,
ghost echoes can be recognised as such by switching over the pulse length on the master radar.
☞
Every pulse length has a particular pulse repetition frequency assigned to it; therefore, when the
pulse length is changed, the repetition frequency changes too.
15.4
Sector Blanking
If the radar function is suppressed in particular sectors (because parts of own ship’s superstructure do
not allow the radar to function in these directions), these sectors are indicated on the PPI near the
compass scale.

2.
Immediately obtain information about the causes of the alarm,
about the system status and about possible system reactions, and - if necessary - immediately perform all necessary
actions for the avoidance of possible danger.
3.
Removing the cause of the alarm: If the alarm has occurred due to a cause that can be removed,
that cause must be removed as quickly as possible; see also Section 29.
Many alarms disappear when the cause disappears. Acknowledgement is then unnecessary.
4.
The alarm must be acknowledged if the situation allows or
requires such acknowledgement:
In the alarm list, press the ACK button or click on the coloured
horn signal. As a result, the alarm which is marked in colour is
usually acknowledged, i.e. it is removed from the alarm list. As
a result of this, alarms which have also been distributed to
other items of equipment within the system are acknowledged
there too. If some other alarm is marked, the alarm which is to
be acknowledged must be marked beforehand by clicking. 1).

List of the Alarm Signal Outputs
The alarm signals mentioned in the following are provided by the radar system in the form of electrical
contacts. Whether the signals are displayed in a given case, and if so in what form, depends on the installation and on the type of alarm system involved. Therefore, no statement about this can be made here.
Radar Alarm
Each radar indicator emits this signal if one of the following alarms is generated:
GYRO FAULT,
INTERSWITCH OFFLINE,
MAGNETRON FAULT,
NO ANTENNA AZIMUTH,
NO HEADMARKER,
NO RADAR VIDEO,
NO TRIGGER,
PLANNING SYSTEM OFFLINE,
POSITION TIMEOUT,

If an appropriate setting has been made at service level, the radar alarm is also emitted if the SYSTEM
FAULT alarm appears.
The radar alarm is also emitted if switch-off of the display electronics unit occurs or if the supply voltage
to the display electronics unit has failed.

Dead Man Alarm Trigger
Every radar indicator emits this signal when any operating action is performed on its keyboard. Therefore,
if the installation has been performed appropriately, there is no need to operate a special watch-alarm
key when a radar indicator is being operated.

2)
For each of the alarm messages mentioned, it is possible to specify at service level that the ARPA alarm should not be triggered.
This alarm leads to the emission of the Chart Alarm signal if, and only if, the To Alarm Panel function is in the switched-on state on the
CHARTPILOT (in the Alarm Settings menu in Chart Mode).

Care
Care of the components of the radar system is limited to occasional cleaning of the screens on the monitors. This should be done with a soft cloth moistened with alcohol.
20.2
Maintenance Work
The ship’s personnel must regularly carry out the following maintenance work:
The cleaning of the filter pad on the Display Electronics Unit and on the TRACKPILOT Electronics
Unit.
If conditions are normal, this work should be done once every 3 months. If the environment is particularly
dusty, it should be done more frequently, and if the air contains very little dust, it can be done less
frequently.
1.
Taking out the filter pad: It is situated on the top of the display electronics unit, and can be gripped
and pulled out by its front left-hand corner without unscrewing the covering cap.
☞
If the display electronics unit is installed in the console, the hinged cover situated below the
operating unit must first be opened.
2.
Cleaning the filter pad: Cleaning can be done by washing in soapy water, or by blowing the dust
out with compressed air, or - depending on the degree of dirtiness - simply by beating the dust out.
3.
Inserting the filter pad: When inserting the filter pad, which must have been dried (if necessary, by
jolting it thoroughly to get the water out of it), make certain that it is seated properly.
Test of the Transmission Power and Receiver Sensitivity of the Radar Transceiver
The test described in Section 21 should be performed at the beginning of every sea voyage, and once a
week during the voyage.

With the Performance Monitor, the transmitter performance and the receiver sensitivity can be checked.
To check the transmitter performance, the antenna gearbox contains an auxiliary antenna in the radiating region of the main antenna. The signal received by this auxiliary antenna is processed and
produces a "good/bad" display. This check thus covers the entire RF transmitting branch of the transceiver, including the magnetron (which is subject to natural aging), the waveguide and the antenna.
The receiver sensitivity is checked by inputting a signal directly at the receiver input, which leads to a
"good" display if, and only if, the amplification is adequate.

During the test, the radar cannot be used for navigation.

Evaluation:
If the sector has a radius of about 16 NM, the transmitting performance is adequate.
☞
The transmitting performance is permitted to drop by 6 dB relative to the nominal performance
and still be regarded as adequate. The sector then still has a radius of approximately 16 NM. If
the transmitting performance drops by more than 6 dB, the sector radius is reduced to 6 NM or
less.
The receiving sensitivity is adequate if the circle has a radius of at least 4 NM.
☞
The receiving sensitivity is permitted to drop by 5 dB relative to the nominal sensitivity and still
be regarded as adequate. The radius of 4 NM corresponds to a reduction of 5 dB.
WARNING:
If these displays do not have the values mentioned, this means that the
performance quality of the radar system is no longer adequate for safe
radar operation. Request service!
☞

Checking / Correcting the Computer Time
As long as the system is receiving the date and time via a connected sensor (e.g. from a GPS receiver),
these data are displayed in the relevant displays of the system, e.g. in the Quick Info Box of the radar
indicator 1). If this external information is missing, the date and time with which the internal clock of the
relevant display electronics unit’s computer is running (computer time) are displayed instead.
So that the displayed time does not change if the sensor fails, a check should occasionally be made on
all radar indicators to make certain that the computer times are in agreement with UTC. If necessary, the
computer times must be corrected.

22.5 Distribution and Deletion of Map Data; Data Saving
Distribution and Deletion of Map Data; Data Saving
New or altered map data must be distributed to all radar indicators on which they are to be displayed. If
necessary, map data can also be deleted. It is recommended that the most recent set of data should be
saved on diskette.
☞
The most recent set of data should be available on all radar indicators (unless there are particular
reasons opposing this). One of the advantages of this is that it prevents loss of the most recent data,
which would occur if map data on an indicator containing old data were edited and if the map data
were then distributed.
File Structure of the Map Data
For the division of the map data into individual files, the earth’s surface is divided up into areas measuring
3° by 3°. All symbols and lines situated in such an area are grouped within a file.
☞ Lines going beyond one of these boundaries are cut at the boundary during the process of division
into files, and are joined together again when the files are called up for the purpose of display or
processing.
Furthermore, the earth's surface is divided up into areas measuring 15° by 15°. All map files belonging
to such an area are grouped within a catalog.
For the designation of the files and catalogs, the south-west corner of the area is used in all cases;
files have the file extension .D03, and catalogs have the extension .D15:
The file S39E144.D03 contains all map data situated in the area bounded by the 39th and 36th
southern lines of latitude and by the 144th and 147th eastern lines of longitude.
The catalog N15W075.D15 contains all map files of the data that are situated in the area bounded
by the 15th and 30th northern lines of latitude and by the 75th and 60th western lines of longitude.
☞
Just as a map file and the catalog are automatically created as soon as a symbol or line is edited
for the defined area, so are the file and (if applicable) the catalog deleted again as soon as there
are no longer any symbols and lines (or parts of lines) present in the area defined for the file and
catalog.
Transferring Map Files to Other Radar Indicators
1.
Click on the index card Tools.
2.
Click on Map Transfer, then on Transmit.
3.
Click on the field under Destination. Mark the indicator to which the data are to be transferred, or
All indicators if the data are to be transferred to all installed radar indicators.
☞ The indicator designations listed here are identical to those entered in the header bar of the
System Maintenance Manager. If in doubt, switch on the System Maintenance Manager of the
destination unit, and have a look.
4.
In the Files in Source list, mark the catalog or file that is to be transferred. If all files are to be transferred, mark the list entry at the top, designated by "/". By clicking on the Add >> button, put the
marked files and catalogs into the Files to Transfer list.
5.
Repeat procedure 4 for other files/catalogs that are to be transferred.
☞
