◆◆◆PRECAUTIONS BEFORE OPERATION◆◆◆
■Cautions for high voltage
High voltages from hundreds volts to tens of thousands volts are to be applied to the electronic
equipment such radio and radar devices. You do not face any danger during normal operation,
but sufficient cares are required for maintenance, inspection and adjustment of their internal
components. (Maintenance, check-up and adjustment of the inside of the equipment are
prohibited except by maintenance specialists.)
High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from
electric shock, but even voltages of hundred volts may sometimes lead to a death from electric
shock. To prevent such an accident, make it a rule to turn off the power switch, discharge
capacitors with a wire surely earthed on an end make sure that internal parts are no longer charged
before you touch any parts inside these devices. At the time, wearing dry cotton gloves ensures
you further to prevent such danger. It is also a necessary caution to put one of your hands in the
pocket and not to use your both hands at the same time.
It is also important to select a stable foothold always to prevent additional injuries once you were
shocked by electricity. If you were injured from electric shock, disinfect the burn sufficiently
and get it taken care of promptly.
■What to do in case of electric shock
When finding a victim of electric shock, turn off the power source and earth the circuit
immediately.
If it is impossible to turn off the circuit, move the victim away promptly using insulators such as
dry wood plate and cloth without touching the victim directly.
In case of electric shock, breathing may stop suddenly if current flows to the respiration center in
the brain. If the shock is not so strong, artificial respiration may recover breathing. When
shocked by electricity, the victim will come to look very bad with weak pulse or without beating,
resulting in unconsciousness and rigidity. In this case, it is necessary to perform an emergency
measure immediately.
◆◆◆FIRST-AID TREATMENTS◆◆◆
☆First-aid treatments
As far as the victim of electric shock is not in dangerous condition, do not move him and practice
artificial respiration on him immediately. Once started, it should be continued rhythmically.
(1) Do not touch the victim confusedly as a result of the accident, but the rescuer may also get an
electric shock.
(2) Turn off the power source calmly and move the victim away quietly from the electric line.
(3) Call a physician or ambulance immediately or ask someone to call a doctor.
(4) Lay the victim on this back and loosen his necktie, clothes, belt, etc.
(5) a. Examine the victim’s pulse.
b. Examine his heartbeat bringing your ear close to his heart.
c. Examine his breathing bringing the back of your hand or your face close to his face.
d. Check the size of the pupils of his eyes.
(6) Open the victim’s mouth and take out artificial teeth, cigarette or chewing gum if any.
Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to prevent
the tongue from suffocating. (If it is hard to open his mouth due to set teeth, open it with a
screwdriver and insert a towel in this mouth.)
(7) Then, wipe his mouth so that foaming mucus does not accumulate inside.
☆When pulse is beating but breathing has stopped
(Mouth-to-mouth respiration) Fig. 1
(1) Tilt the victim’s head back as far as this face looks back. (A pillow may be inserted his
neck.)
(2) Push his jaw upward to open his throat wide (to spread his airway).
(3) Pinch the victim’s nostrils and take a deep breath, block his mouth completely with yours
and blow into his mouth strongly. Take a deep breath again and blow into his mouth.
Continue this 10 to 15 times a minutes (blocking his nostrils).
(4) Carefully watch that he has recovered his natural breathing and atop practicing artificial
respiration.
(5) If it is difficult to open the victim’s mouth, insert a rubber or vinyl tube into one of his
nostrils and blow into it blocking the other nostril and his mouth completely.
(6) When the victim recovers consciousness, he may try to stand up suddenly, but let him lie
calmly and serve him with a cup of hot coffee or tea and keep him warm and quiet. (Never
give him alcoholic drinks.)
Method of mouth-to-mouth respiration by raising head
(1) Raise the victim’s head. Support his
forehead with one of your hand and his
neck with the other hand. →1
When you tilt his head backward, the
victim, in most cases, opens his mouth to
the air. This makes mouth-to mouth
respiration easy.
(2) Cover his mouth as widely as possible with
yours and press your cheek against his nose
→2
or, pinch his nostrils with your fingers to
prevent air from leaking. →3
(3) Blow into his lungs. Continue blowing
into his mouth until his breast swells.
Blow into his mouth as quickly as possible
for the first 10 times.
Fig. 1 Mouth-to mouth respiration
☆When both pulse and breathing have stopped
Perform the (Cardiac massage) Fig. 2 and (Mouth-to-mouth respiration) Fig. 1
When no pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac arrest
is supposed to have occurred and artificial respiration must be performed.
(1) Place your both hands, one hand on the other, on the lower one third area of his breastbone
and compress his breast with your elbows applying your weight on his breast so that it is
dented about 2cm (Repeat compressing his breast 50 times or so a minutes). (Cardiac
massage)
(2) In case of one rescuer,
Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat
this combination.
In case of two rescuers,
One person repeats cardiac massages 15 times while the other person blow into his mouth
twice, and they shall repeat this combination. (Perform the cardiac massage and
mouth-to-mouth respiration)
(3) Examine his pupils and his pulse sometimes. When the both have returned to normal, stop
the artificial respiration, serve him with a cup of hot coffee or tea and keep him warm and
calm while watching him carefully. Commit the victim to a medical specialist depending
on his condition. (Never give him alcoholic drinks.) To let him recover from the mental
shock, it is necessary for persons concerned to understand his situations and the necessary
treatment.

●PRECAUTIONS●
DANGER
Never carry out internal inspection or repair work of the
equipment by users.
Inspection or repair work by uncertified personnel may
result in fire hazard or electrocution.
For inspection and repair work of equipment components,
consult with our branch office, branch shop, sales office,
or our distributor in your district.
When conducting maintenance, make sure to turn the main
power off.
Failure to comply may result in electrocution.
Turn off the main power before cleaning the equipment.
Especially when a rectifier is used, make sure to turn it off
since voltage is still outputted from the rectifier even after
the indicator and the radar are turned off. Failure to
comply may result in equipment failure, or death or serious
injury due to electric shock.
When conducting maintenance work on the scanner, make
sure to turn its main power off.
Failure to comply may result in electrocution or injuries.
Make sure to turn off the scanner safety switch. Failure to
comply may result in injuries caused by physical contact
with the rotating scanner.
Do not touch the radiator. Even if the power is turned off,
the radiator may be rotated by the wind.
- iv -
WARNING
Never directly touch the internal components of the
scanner or indicator. Direct contact with these
high-voltage components may cause electrocution. For
maintenance, inspection, or adjustment of equipment
components, consult with our branch office, branch shop,
sales office, or our distributor in your district.
To contact our sales department, branch offices, branch
shops, and sales offices:
Please refer to the "Office List" at the end of the document.
Do not get close to the radiant section of the scanner. It is
a rotating part, and it may cause injuries if it suddenly
starts rotating and consequently hits the body. It is
recommended that the radiant section be installed at a high
place such as on the roof of the wheelhouse, on the flying
bridge, on the trestle, or on the radar mast so that no one
can get close to it. When any work must be done on the
scanner, make sure to turn the safety switch off.
Microwave radiation level:
Keep out from a distance closer than that specified below
for each type of scanner when it is transmitting. Being
within the specified distance from the center of the front
face of the scanner may cause microwave exposure which
could result in injuries (especially of the eyes).
NKE-600-2F2T/2254 (radiation levels: 10 W/m2): 0.6 m
NKE-600-2C1T (radiation levels: 10 W/m2): 1.1 m
NKE-600-2C1T (radiation levels: 100 W/m2): 25 cm
Make sure to install the scanner at a place higher than
human height.
Direct exposure to electromagnetic waves at close range
will have adverse effects on the human body.
- v -
WARNING
Do not change MBS Level/Area unless absolutely
necessary.
Incorrect adjustment will result in deletion of nearby target
images and thus collisions may occur resulting in death or
serious injuries.
When cleaning the display screen, do not wipe it too
strongly with a dry cloth. Also, do not use gasoline or
thinner to clean the screen. Failure to comply will result
in damage to the screen surface.
Direct exposure to electromagnetic waves at close range
will have adverse effects on the human body. When it is
necessary to get close to the scanner for maintenance or
inspection purposes, make sure to turn the indicator power
switch to "OFF" or "STBY."
Direct exposure to electromagnetic waves at close range
will have adverse effects on the human body.
When conducting maintenance work, make sure to turn off
the power and unplug the power connector J1 of the radar
process unit so that the power supply to the equipment is
completely cut off.
Some equipment components can carry electrical current
even after the power switch is turned off, and conducting
maintenance work without unplugging the power
connector may result in electrocution, equipment failure, or
accidents.
When disposing of used lithium batteries, be sure to
insulate the batteries by attaching a piece of adhesive tape
on the + and - terminals. Failure to comply may cause
heat generation, explosion, or fire when the batteries get
shorted out.
- vi -
CAUTION
A malfunction may occur if the power is instantaneously
interrupted during operation of the radar. In this case, the
power should be turned on again.
Normally, use the automatic tune mode.
Use the manual tune mode only when best tuning is not
possible in the automatic tune mode due to deterioration of
magnetron.
If the gain is too high, unnecessary signals including
receiver noise and false video increase resulting in
reduction of visibility of targets.
On the contrary, if the gain is too low, targets including
ships and dangerous objects may not be clearly indicated.
When using the sea clutter suppression function, never set
the suppression level too high canceling out all image
noises from the sea surface at close range.
Detection of not only echoes from waves but also targets
such as other ships or dangerous objects will become
inhibited.
When using the sea clutter suppression function, make
sure to choose the most appropriate image noise
suppression level.
When using the rain / snow clutter suppression function,
never set the suppression level too high canceling out all
image noises from the rain or snow at the close range.
Detection of not only echoes from the rain or snow but also
targets such as other ships or dangerous objects will
become inhibited.
When using the rain / snow clutter suppression function,
make sure to choose the most appropriate image noise
suppression level.
- vii -
CAUTION
Use the radar only as a navigation aid.
The final navigation decision must always be made by the
operator him/herself.
Making the final navigation decision based only on the
radar display may cause accidents such as collisions or
running aground.
Use target tracking function only as a navigation aid. The
final navigation decision must always be made by the
operator him/herself.
Making the final navigation decision based only on
tracking target information may cause accidents.
Tracking target information such as vector, target
numerical data, and alarms may contain some errors.
Also, targets that are not detected by the radar cannot be
acquired or tracked.
In setting an automatic acquisition zone, it is necessary to
adjust the gain, sea clutter suppression and rain clutter
suppression to ensure that target echoes are displayed in
the optimum conditions. No automatic acquisition zone
alarms will be issued for targets undetected by the radar,
and this may cause accidents such as collisions.
Target Tracking Function Test is provided to test if the
target tracking function is operating normally. Thus, do
not use the function except when you test the target
tracking function.
In particular, if the operation test mode is used during
operation, pseudo targets appear on the radar display and
they are confused with actual targets.
Do not use the mode during navigation.
Otherwise, an accident may result.
- viii -
CAUTION
If a great value is set as a condition for deciding targets as
identical, a tracking target near an AIS target is regarded as
identical to the AIS target and it may not be displayed any
more.
For example, when a pilot boat (which is a small target not
being tracked) equipped with an AIS function approaches a
cargo ship as a tracking target not equipped with an AIS
function, the tracking target symbol of the cargo ship may
not be displayed any more.
These alarms may include some errors depending on the
target tracking conditions.
Making the final decision based only on the alarm may
cause accidents such as collisions.
Any adjustments must be made by specialized service
personnel.
Incorrect settings may result in unstable operation.
Do not make any adjustments during operation. Failure to
comply may result in adverse effects on the radar function
which may lead to accidents or equipment failure.
Optimal values have been set for Video Level and Vector
Constant; therefore, never change their values unless
absolutely necessary. Failure to comply may result in
accidents that would lower target tracking performance.
Do not change the quantization level settings unless
absolutely necessary. If set at an inappropriate value, the
target acquisition or target tracking function deteriorates,
and this may lead to accidents.
Any adjustments must be made by specialized service
personnel.
Failure to comply may result in accidents or equipment
failure.
- ix -
CAUTION
Make sure to shut off the main power before replacing
parts. Failure to comply may result in electrocution or
equipment failure.
When replacing magnetrons, make sure to shut off the
main power and let the equipment stand for more than 5
minutes to discharge the high-voltage circuit. Failure to
comply may result in electrocution.
Make sure to take off your watch when your hand must get
close to the magnetron.
Failure to comply may result in damage to the watch since
the magnetron is a strong magnet.
Make sure that two or more staff member work together
when replacing the LCD. If only one person attempts to
replace the LCD, he/she may drop it and become injured.
Do not directly touch the inverter circuit of the LCD display
with a bare hand since high voltage temporarily remains in
the circuit even after the main power is shut off.
Failure to comply may result in electrocution.

1.2 FEATURES
Realization of Large, Easy-to-see Screen with High Resolution
The 19-inch color LCD with high resolution of 1280 × 1024 pixels can display radar images of 250 mm or
more in diameter. Even short-range targets can also be displayed as high-resolution images.
Target Detection by Latest Signal Processing Technology
The system employs the latest digital signal processing technology to eliminate undesired clutter from the
radar video signals that are obtained from the receiver with a wide dynamic range, thus improving the target
detection.
Advanced Technology Based Target Tracking (TT) Functions (Option)
The target acquisition and tracking performance is enhanced by the use of the fastest DSP and tracking
algorithm. So stable operation in target tracking under clutter is ensured.
• Acquisition and tracking of 100 targets for High performance edition, 30 targets for Normal edition.
• Hazardous conditions are represented by shapes and colors of symbols as well as sounds.
• Trial maneuvering functions provided. (High performance edition)
• Tracks of up to 20 target ships can be stored with a maximum of 1,500 points for each of them, and
displayed distinguished by using 7 different colors.
Note: ARPA/ATA Process Unit must be fitted on ships compliant to IMO.
Overlay of Radar Images, Coastlines, and Track
As well as operator-created NAV lines, the data of coastlines, objects such as buoys, and target tracks / AIS
tracks, which is stored on the memory card can be superimpose-displayed with radar images and radar trails
in all display modes including the head-up mode.
Creation / display of marks and lines (up to 2000 items).
Use of the optional plotter function enables the own track display distinguished by using 7 different colors,
creation of marks and lines (up to 20000 items) and the settings of waypoints / courses.
Easy Operation with GUI
All the radar functions can be easily controlled by simply using the trackball and 2 switches to operate the
buttons shown on the radar display.
Improved Day / Night Mode
Five types of background colors are available in Day / Dusk / Night mode.
Each background color can be reproduced to be suited for the user’s operating environment by simple key
operation. The radar echoes and a variety of graphics can also be represented in different colors, ensuring
easy-to-see displays.
1-3
Self-diagnostic Program Incorporated
The Self-diagnostic program always monitors all the functions of the system. If any function deteriorates,
an alarm message will appear on the radar display and an alarm sounds at the same time. Even when the
system is operating, the functionality test can be carried out. (except on some functions)
Performance Monitor (Option)
The radar performance (transmitted output power and receiving sensitivity) can appear on the radar display.
Note: Performance monitor must be fitted on ships compliant to IMO.
Easy Interswitch Operation (Option)
If an interswitch unit (option) is connected, up to four JPL-600-MK2 radars can be switched over by
performing simple operation.
* An interswitch (NQA-3201) is needed separately.
Various Functions
• RADAR Trails

z Wait for about 2 seconds before turning on the
power again.
z Immediately after the radar is installed, at start of the
system after it has not been used for a long time, or
after the magnetron is replaced, preheat the
equipment in the standby state for 20 to 30 minutes
before setting it into the transmit state.
z If the preheating time is short, the magnetron
causes sparks, resulting in its unstable oscillation.
Start transmission on a short-pulse range and
change the range to the longer pulse ranges in turn.
If the transmission is unstable in the meantime,
immediately place the system back into the standby
state and maintain it in the standby state for 5 to 10
minutes before restarting the operation.
Repeat these steps until the operation is stabilized.

3.9.3 Overview of Function Operations (User Function Setting)
The following outlines the operation of each function selected from the function setting menu.
Procedures 1 Press the [FUNC] key for 2 seconds.
The User Function Setting menu will appear.
Specify the number for the function for which the settings are to be changed.
The following are the operation overviews of each function setting item.
[Page 1] [1] Mode
• Selects the function name to be indicated at the lower left of the display when the function is
selected.
• When the setting is changed back to the factory setting, the initial value of the selected mode is
called.
• The following 11 modes are provided.
Coast : Use this mode to monitor a relatively short range, for example, bays and
coasts where many boats and ships are running. (Importance is attached to
resolution.)
Deepsea : Use this mode to monitor a relatively long range.
(Importance is attached to long-range gain.)
Fishnet : Use this mode to detect small targets hidden by sea clutter returns.
(Importance is attached to sea clutter suppression, and gain to moving targets
lowers.)
Storm : Use this mode when many rain / snow clutter returns or sea clutter returns
are detected in stormy weather. (Importance is attached to rain / snow
clutter and sea clutter suppression, and gain slightly lowers.)
Calm : Use this mode when only a few rain / snow clutter returns or sea clutter
returns are detected.
Rain : Use this mode when sea clutter is not strong but rain / snow clutter is strong.
(Importance is attached to rain / snow clutter suppression, and gain slightly
lowers.)
Bird : Use this mode to detect flocks of sea birds.
Long : Use this mode to monitor utmost distances in the broad ocean.
Buoy : Use this mode to detect small targets like radio buoys in areas outside the
sea clutter area. (This mode displays targets of which detection probability
is low.)
User1 : General mode used when the nine modes above are not applicable.
User2 : General mode used when the nine modes above are not applicable.
[Page 1] [2] IR (Interference Rejection)
• Same function as IR described in Section 3.4.1.
3-97
[Page 1] [3] Process (Video Process)
• Same function as Process described in Section 3.4.4.
[Page 1] [4] Target Enhance
• Same function as Target Enhance described in Section 3.4.3.
[Page 1] [5] Auto STC / FTC (Auto Sea / Rain)
• Detects unwanted waves such as rain / snow clutter and sea clutter and automatically suppresses
them.
• When the sea state or weather changes, this function automatically performs suppression
processing in accordance with the situation.
• Suppression processing is not full automatic, and requires the operator to adjust the afterimages of
unwanted waves.
• To adjust the afterimage of sea clutter, use the [SEA] dial.
• To adjust the afterimage of rain / snow clutter, use the [RAIN] dial.
• In areas where the density of unwanted waves is low, unwanted waves may remain being judged
as targets. Thus, use the automatic clutter suppression mode together with the video process
mode.
• Characteristics of the automatic clutter suppression function.
Off : Disables the automatic clutter suppression function.
Select off when rain / snow clutter and sea clutter are not strong.
AUTO Sea : Automatically detects the strength of sea clutter, and performs the
most suitable sea clutter suppression processing.
Even when the strength of sea clutter varies depending on the
wind direction, AUTO Sea performs the most suitable suppression
processing.
Land like islands can be displayed naturally.
Since rain clouds outside sea clutter areas are recognized as land,
there is no effect of suppressing rain / snow clutter.
AUTO Sea/Rain : Along with AUTO Sea, AUTO Rain automatically detects the
strength of rain / snow clutter, and performs the most suitable rain
/ snow clutter suppression processing.
When rain clouds are scattered about, AUTO Rain performs rain
/ snow clutter suppression processing for only the rain-cloud areas.
Since land is recognized as rain clouds, land videos become
obscure.
[Page 2] [1] - [7] Pulse Length
• Sets the standard transmitter pulse length in each range.
• When the range is called, the pulse range is used.

[Page 4] [1] - [7] Trails Setting
• Same functions as in the Trails Setting menu described in Section 3.8.2.
[Page 5] [1] Gain Offset
• Corrects gain while the function mode is called.
• Since the displayed noise level varies depending on the combination of the video process mode
and the interference rejection level, gain needs fine adjustment for always obtaining the highest
level.
• The gain correction function saves the correction value set by the gain adjust in each function
mode, so it can obtain the highest gain without the gain adjust being operated when the function
mode is changed.
• To set high gain, set a value on the “+” side.
• To set low gain, set a value on the “-” side.
• When the radar interference rejection level is increased, the noise level is lowered. Thus, set a
gain correction value to the “+” side.
• When the video process mode 3Scan CORREL , 4Scan CORREL , or 5Scan CORREL is
used, the noise level is lowered. Thus, set a gain correction value to the “+” side.
• When the video process mode Remain or Peak Hold is used, noise is hard to disappear.
Thus, set a gain correction value to the “-” side.
[Page 5] [2] PRF
• Same function as in the Pulse Repetition Frequency described in 3.8.3.
[Page 5] [3] Small Buoy Detection
• When the automatic sea clutter suppression function is used, this mode is used to process signals
for detecting small targets.
Off : Activates the general signal processing mode.
On : The signal processing mode for detecting small targets.
[Page 5] [4] Fishnet Detection
• Use this mode to detect small targets hidden by sea clutter returns.
• The simultaneous use with the automatic rain / snow clutter suppression function will increase
effects.
Off : Activates the general signal processing mode.
On : Activates the fishnet detection mode.
[Page 5] [5] Antenna Height
• Set the height of radar antenna above sea level.
• The STC/FTC curve is changed.
-5m : Set the antenna height under 5m.
5-10m : Set the antenna height 5m to 10m.
10-20m : Set the antenna height 10m to 20m.

z There are the following limitations on use of the target
acquisition and target tracking functions.
[I] Resolution between adjacent targets and swapping
during automatic target tracking
Depending on the particular distance and echo size,
resolution between adjacent targets during automatic target
tracking usually ranges somewhere between 0.03 to 0.05 NM.
If multiple targets approach each other, resolution will
become about 0.05 NM and this may cause the system to
regard them as one target and thus to swap them or lose part
of them. Such swapping or less of targets may also occur if
the picture of the target being tracked is affected by rain/snow
clutter returns or sea clutter returns or moves very close to
land.
[II] Intensity of echoes and the target tracking function
The intensity of echoes and the tracking function have a
correlationship, and thus the target will be lost if no echoes
are detected during six scans in succession. If a lost target
exists, therefore, radar gain must be increased to support
detection of the target. If, however, radar gain is increased
too significantly, sea clutter returns or other noise may be
erroneously detected and tracked as a target, and resultingly,
a false alarm may be issued.
[III] Adverse effects of error sources on automatic
tracking
To execute accurate tracking, it becomes necessary first to
appropriately adjust the [GAIN], [SEA] and [RAIN] dials of the
radar so that the target to be acquired and tracked id clearly
displayed on the radar display. Inappropriate settings of
these adjustments reduce the reliability / accuracy of
automatic tracking.

5.1.1 Collision Avoidance
Problems of Collision Avoidance in Navigation
Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be
described briefly who the collision avoidance is positioned among the navigational aid problems.
The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the media
through which the mobile craft travels, whether air, water, the boundary between air and water, or space. This
pattern consists of two closed loops in principle, one of which is a collision with another mobile craft and the
other is a loop of finding a right and safe way to reach a predeterminate destination. Fig. 5-1 shows the
conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop of collision avoidance is
shown on the left side and the closed loop of finding a right course on the right side.
Fig. 5-1 Navigation Pattern
Marine Accidents and Collisions
Among marine accidents, collision accidents have been highlighted as the tonnages and speeds of ships become
higher along with the increase in traffic at sea. If a tanker carrying dangerous articles such as crude oil
collides with any other vessel, then not only the vessels involved with the accident but other vessels in the
vicinity, port facilities, inhabitants in the coastal area as well as marine resources may also suffer immeasurable
damages and troubles. Collision accidents have a high percentage of the marine accidents that have occurred
in recent years. To cope with these problems, any effective measures are needed and some equipment to
achieve collision avoidance requirements have been developed at rapid strides.

Basic Concept of Collision Avoidance
There are two aspects in collision avoidance: collision prediction and avoidance. Collision prediction is to
predict that two or more vessels will happen to occupy the same point at the same time, while collision
avoidance is to maneuver vessels not to occupy the same point at the same time.
In practical operation of vessels, a spot of collision has to be deemed to be a single point but a closed zone.
This closed zone is conceptually defined as a CPA (Closest Point of Approach). In collision prediction, the
time to be taken until a ship reaches the CPA is defined as a TCPA (Time to CPA).
Fig. 5-2 shows a diagram caked “Collision Triangle”.

Relative Vector and True Vector
From two points of view, collision prediction and avoidance, it is necessary to obtain the relative vector of other
ship for prediction and the true vector of other ship for collision avoidance in order to grasp other ship’s aspect.
The relationship between the relative vector and true vector is shown in Fig. 5-3.
Both rough CPA and TCPA can be obtained easily from the relative speed vector of other ship. This method
has an advantage that the risks of collision with all other ships within the radar range can be seen at a glance.
On the other hand, the course and speed of other ship can easily be obtained from its true speed vector, enabling
other ship’s aspect to be seen at a glance. Thus, the aspects of other ships (transverse, outsail, parallel run,
reverse run, etc...) as described in the act of prevention of collision at sea can be readily grasped. If there is a
risk of collision with other ship, the operator can determine which rule to be applied and how to operate own
ship.

Radar and Collision Avoidance
Radar is still playing an important roll for collision prevention and positioning. A plotter is used to further
enhance the radar functionality. The plotter is capable of plotting other positions of other ships in 3 to 6
minute intervals to monitor their movement. The plots of other ships represent their tracks relative to own
ship, and it is shown whether there is a risk of collision, namely CPA and TCPA can be obtained. This method
using a plotter is fairly effective, but the number of target ship, which is manually plotted, is limited and it takes
several minutes to measure those.

5.2 TARGET TRACKING OPERATION
This section explains how to use the target tracking function.
The target tracking function automatically tracks a target, and displays the target's course and speed as
vectors.
The target tracking function calculates CPA and TCPA, and issues an alarm as needed.
The tracking data is erased from memory when the power is turned off or during transmission standby.
CAUTION
Tracking target information such as vector, target
numerical data, and alarms may contain some errors.
Also, targets that are not detected by the radar cannot be
acquired or tracked.
In setting an automatic acquisition zone, it is necessary to
adjust the gain, sea clutter suppression and rain clutter
suppression to ensure that target echoes are displayed in
the optimum conditions. No automatic acquisition zone
alarms will be issued for targets undetected by the radar.

CAUTION
These alarms may include some errors depending on the
target tracking conditions.
In the system, targets are categorized into two types: tracked / activate AIS targets and dangerous targets.
The grade of danger can easily be recognized on the display at a glance. So the officer can easily decide
which target he should pay attention to.
It is not possible to switch off the tracked target visual alarm, unless tracking is ceased, or the alarm
condition no longer applies.

Alarm for New Target Acquired in Automatic Acquisition Zone (New Target)
CAUTION
In setting an automatic acquisition zone, it is necessary to
adjust the gain, sea clutter suppression and rain clutter
suppression to ensure that target echoes are displayed in
the optimum conditions. No automatic acquisition zone
alarms will be issued for targets undetected by the radar.
The automatic acquisition function sets a zone in a range and issues an alarm when a new target (which is
not yet acquired) goes into this zone.
For the setting of an automatic acquisition zone, refer to " Acquiring Target " in Section 5.2.1.

Lost Target Alarm
When it is impossible to continue tracking any acquired and tracked target, or the data of AIS target cannot
received for a specified time, the LOST alarm will be generated. The typical causes for alarm
generation are shown below, but not limited to the following:
• The target echo is very weak.
• The target is shadowed by a shore or a large ship and its echo is not received.
• The target echo is blurred by sea clutter returns.
If a target under tracking goes out of a range of 32 nm and can no longer be tracked, it is canceled without a
lost target alarm.

z Trial maneuvering is to simulate own ship’s course and
speed in the conditions that the course and speed of a
target ship are unchanged as they are. As the
situation is different from any actual ship
maneuvering, set values with large margins to CPA
Limit and TCPA Limit.
5.7 TRIAL MANEUVERING
(TRIAL MANEUVER)
(Not used on the JPL-600-MK2 for VTS)
The trial maneuvering is the function of simulating own ship’s course and speed for collision avoidance
when a dangerous target appears. When the own ship's course and speed are entered in manual mode, the
trial maneuvering function checks if pre-acquired or pre-activated targets are dangerous.
The ranges of course and speed to be entered manually:
Course: 360 ° (in 0.1 ° intervals)..........................................................................[EBL] dial

The radar operator has a role of interpreting the radar displays to provide his best aid in maneuvering the
ship. For this purpose, the operator has to observe the radar displays after fully understanding the
advantages and disadvantages that the radar has. For better interpretation of radar display, it is important
to gain more experiences by operating the radar equipment in fair weathers and comparing the target ships
watched with the naked eyes and their echoes on the radar display.
Various types of radar display will be explained below.
6.1 RADAR WAVE WITH THE HORIZON
Radar beam radiation has the nature of propagating nearly along the curved surface of the earth.
The propagation varies with the property of the air layer through which the radar beam propagates.
In the normal propagation, the distance (D) of the radar wave to the horizon is approximately 10% longer
than the distance to the optical horizon. The distance (D) is given by the following formula:
D=2.23( h2h1 +)(nm)
h1: Height (m) of radar scanner above sea level
h2: Height (m) of a target above sea level
Figure 6. is a diagram for determining the maximum detection range of a target that is limited by the curve
of the earth surface in the normal propagation.

When the height of scanner is 10 m for instance,
(a) A target that can be detected at the radar range of 64 nm on the radar display is required to have a
height of 660 m or more.
(b) If the height of a target is 10 m, the radar range has to be approx. 15 nm. However, the maximum
radar range at which a target can be detected on the radar display depends upon the size of the target
and the weather conditions, that is, the radar range may increase or decrease depending upon those
conditions.

6.2 STRENGTH OF REFLECTION FROM
THE TARGET
The signal intensity reflected from a target depends not only on the height and size of the target but also on
its material and shape. The echo intensity from a higher and larger target is not always higher in general.
In particular, the echo from a coast line is affected by the geographic conditions of the coast.
If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display.
Therefore, the distance to the coast line should be measured carefully.

Figure 6.3
Table 6.1 shows the graph indicating the relation between the target detection distance and the radar
reflection cross-sectional area (RCS) with regard to the type and the height of the target in a situation in
which the weather is good, the sea state is calm and the radio wave propagation is normal. As revealed by
this table, even on the same sea shore line, detection distance greatly differs depending on the height of the
target from the surface of the sea. Furthermore, because the target detection distance is greatly influenced
by the shape and material of the target and environmental conditions, such as the sea state, weather, and
radio wave propagation, caution should be taken when detecting distance of target.

6.3 SEA CLUTTER AND RAIN AND SNOW
CLUTTER
In addition to the echo required for observing ships and land radar video image also includes unnecessary
echo, such as reflection from waves on the sea surface and reflection from rain and snow. Reflection from
the sea surface is called "sea clutter," and reflection from rain and snow is called "rain and snow clutter,"
and those spurious waves must be eliminated by the clutter rejection function.
[I] Sea clutter
Sea clutter appears as an image radiating outwardly from the center of the radar display and changing
depending on the size and the shape of waves. Generally, as waves become larger, image level of the
sea clutter is intensified and the clutter far away is also displayed. When waves are large and the sea
clutter level is high, it is difficult to distinguish sea clutter from a small boat whose reflection intensity
is weak. Accordingly, it is necessary to properly adjust the sea clutter rejection function. Table 6.2
shows the relation between the sea state (SS) showing the size of waves generated by wind and the
radar's detection probability.

As shown in Table 6.3, the number of SS increases as the wind speed becomes high and the waves
become large. Table 6.2 reveals that detection probability decreases from V (80 %) to NV (less than
50 %) as the number of SS increases. Therefore, even if the sea state is calm and a target clearly
appears on the radar display, when the sea state becomes rough, target detection probability decreases
resulting in difficulty of target detection by the radar.
Table 6.3 Relation between Douglas sea state and average wind speed and significant wave
height
Significant wave height: an average of top N/3 higher waves when the
number of waves detected within a constant time
duration is N
For example, in the case of a standard marine buoy, RCS of X band radar is 5 m2 as shown in Table 6.1.
When observing such a target in the sea state (SS3) in which significant wave height exceeds 1.2
meters, detection probability is M-NV, as shown in Table 6.2, which indicates 50 % or less.
[II] Rain and snow clutter
Rain and snow clutter is a video image that appears in a location where rain or snow is falling. The
image changes according to the amount of rain (or the amount of snowfall). As precipitation
increases, the image of rain and snow clutter becomes intensified on the radar display, and in the case
of localized heavy rain, an image similar to the image indicating land is displayed in some cases.
Furthermore, because radio waves tend to attenuate due to rain and snow, the ability to detect a target
in the rain and snow clutter or a target beyond the rain and snow clutter may decrease. The amount of
attenuation depends on the transmission frequency, antenna beam width, and the pulse length. Figure
6.3 and Figure 6.4 show examples in which detection distance is reduced due to the influence of
precipitation. Because of this, a target, which clearly appeared up to 10 NM by an X band radar
(pulse width of 0.8 μs) when it was not raining, may become dimly visible up to 5 NM when the
amount of rain becomes 4 millimeters per hour. Furthermore, when comparing the X band radar with
the S band radar, target detection distance decreases less when an S band radar is used, which means it
is influenced less by precipitation.

[III] Coping with sea clutter and rain and snow clutter
When the weather is bad and the ocean is rough, the use of an S band radar is effective because the
radar is not influenced by sea clutter so much and attenuation due to rain drops is small. When an X
band radar is used, reducing the pulse width will reduce the influence by spurious waves, and also the
spurious wave rejection function effectively works; therefore, the use of short pulse is effective when
the weather is bad. By using image processing functions PROC 1 to 3, it is expected that spurious
waves are further suppressed. Since optimal settings for those items can be automatically made by
using the function mode, it is recommended that FUNC Storm or FUNC Rain be used by
selecting the function mode when the weather is bad. For details of the function mode, see Chapter
3.9.
However, these functions may make some targets invisible, particularly targets with higher speeds.
6-9
6.4 FALSE ECHOES
The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes
appear by the following causes that are well known:
[I] Shadow
When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction
of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the
funnel or mast. Whether there are some false echoes due to shadows can be checked monitoring the
sea clutter returns, in which there may be a part of weak or no returns.
Such shadows appear always in the same directions, which the operator should have in mind in radar
operation.
[II] Side Lobe Effect
A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar
display. This type of false echo can easily be discriminated when a target echo appears isolated.
(See Figure 6.5)
HL
Figure 6.5
[III] False Echo by Secondary Reflection
When a target exists near own ship, two echoes from the single target may appear on the radar display.
One of those echoes is the direct echo return from the target and the other is the secondary reflection
return from a mast or funnel that stands in the same direction as shown in Figure 6.6.

[IV] False Echo by Multiple Reflection
When there is a large structure or ship with a high vertical surface near own ship as shown in Figure
6.7, multiple refection returns may appear on the radar display. These echoes appear in the same
intervals, of which the nearest echo is the true echo of the target.
Figure 6.7
[V] Second Time Echoes
The maximum radar detection range depends upon the height of the scanner and the height of a target
as described in the section of “The Horizon for Radar Beam Radiation”. If a so-called “duct” occurs
on the sea surface due to a certain weather condition, however, the radar beam may propagate to a
abnormally long distance, at which a target may be detected by the radar.
For instance, assuming that the pulse length is MP3 (on the repetition frequency of 1400 Hz), the first
pulse is reflected from a target at about 58 NM or more and received during the next pulse repetition
time. In this case, a false echo (second time echo) appears at a position that is about 58 NM shorter
than the actual distance. If the false echo appears at 5 NM on the radar display, the true distance of
the target is 5+58=63 NM. On the pulse length is SP1 (on the repetition frequency of 2250 Hz), a
false echo may appear at a position that is about 36 NM shorter than the actual distance.
This type of false echo can be discriminated by changing over the range scale (the repetition frequency),
because the distance of the target changes accordingly.
If second time echo is appeared, the use of Economy mode in PRF menu is effective. Otherwise,
Stagger Trigger menu set to on. (See section 3.8.3)
6-11
[VI] Radar Interference
When another radar equipment using the same frequency band as that on own ship is near own ship, a
radar interference pattern may appear on the radar display. This interference pattern consists of a
number of spots which appear in various forms. In many cases, these spots do not always appear at
the same places, so that they can be discriminated from the target echoes. (See Figure 6.8)
HL HL
Figure 6.8
If radar equipment causing an interference pattern and this radar are of the same model, their
transmitting repetition frequency is nearly the same. As a result, interference patterns may be
displayed concentrically.
In this case, the interference patterns cannot be eliminated by using only the interference reflector
function, so press [TX/PRF] key several times to fine-tune the transmitting repetition frequency.
An interference suppressing effect can be heightened by applying a different transmitting repetition
frequency to the interference pattern source radar and this radar.

The SART (Search and rescue Radar Transponder) is a survival device authorized by the GMDSS (Global
Maritime Distress and Safety System), which is used for locating survivors in case that a distress accident
occurs at sea. The SART is designed to operate in the 9 GHz frequency band.
When receiving the 9 GHz radar signal (interrogating signal) transmitted from the radar equipment on a
rescue ship or search aircraft, the SART transmit a series of response signals to inform the distress position
to the rescue and search party.
* This radar provides a shortcut item to make settings for SART signal reception. Execution of this item
automatically switches to the setting for SART reception.
It also functions for detect the beacon or target enhancer.

Precautions in Mounting the Cover
When the cover is removed for regular checkup and replacement of parts and refitted after such work, the
procedures of fastening bolts shall be taken with the following precautions:
(a) The proper fastening torque of the fitting bolts (M8) is 1176 to 1470 N-cm (120 to 150 kgf-cm) (which
makes the inside water-tight and protects the packing against permanent compressive strain).
The packing start producing from the cover at a torque of approximately 1470N-cm (150 kgf-cm).
Do not fasten the bolts with a torque exceeding the specified value. Otherwise, the screws may be
broken.
(b) Use an offset wrench of 11 mm × 13 mm or a double-ended wrench of 13 mm × 17 mm (not longer
than 200 mm).
(c) Screw all the bolts by hand first to prevent them playing, then fasten them evenly in order not to cause
one-sided fastening. (Fasten the bolts with 25 % of the required torque at the first step.)
*: Fasten the bolts in the diagonal order.

z If the radiator front face (radiation plane) is soiled with
smoke, salt, dust, paint or birds’ droppings, wipe it
with a piece of soft cloth wetted with alcohol or water
and try to keep it clean at all times. Otherwise, radar
beam radiation may attenuate or reflect on it, resulting
in deterioration of radar performance.
z Never use solvents of gasoline, benzine,
trichloroethylene and ketone for cleaning.
(1) Radiator
Check up and clean the radiator.
(2) Rotating section
(a) Supply Oil Seal
An scanner unit with a grease nipple needs grease supply. Remove the cap of the grease nipple
on the front of the radiator support, and supply grease with a grease gun.
Make the oiling every six months. The oil quantity shall be approximately 100 g, which is as
much as the grease comes out of the oil seal. Use the grease of Mobilux 2 of Mobil Oil.
(b) Oiling gears
Apply grease evenly to the tooth surfaces of the main shaft drive gear and the encoder drive gear
with a spreader or brush. Oiling in short intervals is more effective to prevent the gears from
wear and tear and extend their service life, but oil at least every six months.
Use Mobilux2 of Mobile Oil.
(c) Mounting legs
Check the mounting legs and mounting bolts of the scanner unit case for corrosion at intervals
and maintain them to prevent danger. Apply paint to them once a half year because painting is
the best measure against corrosion.

9.1 FAULT FINDING
In case of semiconductor circuits, it is deemed that there are few cases in which the used
semiconductor devices have inferior quality or performance deterioration except due to
insufficient design or inspection or by other external and artificial causes. In general, the
relatively many causes are disconnection in a high-value resistor due to moisture, a defective
variable resistor and poor contact of a switch or relay.
Some troubles are caused by defective parts, imperfect adjustment (such as tuning adjustment)
or insufficient service (such as poor cable contact). It will also be effective to check and
readjust these points.
9.1.1 List of Alarms and other Indications
The system automatically recognizes an internal alarm and displays the alarm message. If an
event which is not trouble but must be reported to the operator occurs, the system notifies the
operator of the event.
This section gives the list of alarms displayed by the system and other display lists.
