KB SAFETY INSTRUCTIONS
& WARNING
Radio Frequency Radiation Hazard
The radar antenna emits electromagnetic radio frequency (RF) energy which can be
harmful, particularly to your eyes. Never look directly into the antenna aperture from a
close distance while the radar is in operation or expose yourself to the transmitting
antenna at a close distance.
Distances at whim RF radiation levels ol 100 and 10 W/m? exist are given in the table
below.
Note: If the antenna unit is installed at a close distance in front of the wheel house.
your administration may require halt of transmission within a certain sector of antenna
revolution. This Is possible. Ask your FUFtUNO representative or dealer to provide
this feature.

All come with the EPA (Electronic Planing Aid) fitted standard. An option is available to provide
the lull functionality of ATA (Automatic Tracking Aid). A Video Plotter (Chart Plotter), which
provides Radar Map functions, and Performance Monitor are also optionally available.
The FR-1505 MARK-3 Series is available in the Regular type (Fl-type) and IMO type. The
lMO type is designed as a primary radar under the 1974 SOLAS Convention on ships below
1,600 GT. The R-type satisfies the MO and IEC standards but includes more flexibility of
functionality.
The table below shows the differences between R-type and IMO-type radars. Other functions
and specifications are common. The operator cannot navigate between the two types.

radar receives the radar signal of another
shipbome radar. To retune. press the [STBY/
TX] key twice.
Manual tuning
1. Set up for manual tuning following the
procedure shown below.
2. While observing the picture on the 48 mile
scale, slowly adjust the WM rotary con-
trol to find the best tuning point while
pressing and holding down the HL OFF
control. Make sure that the radar has been
set to the best tuning point. This condi-
tion is where the tuning indicator lights to
about 60% of its total length. Note that
the tuning indication will never extend to
full length.

1.11 Presentation Modes Loss or compass Signal
when the compass signal is lost, the presen-
tation mode automan‘cally becomes head-up
and the compass readout at the screen top
shows asterisks ("'."). Also HEADING FAIL
appears in red characters at the lower-right
comer oi the screen. The message SET
HEADlNG appears at the loweriett corner at
the screen. This alert stays on when the head-
ing signal is restored, to warn the operator that
the readOUt may be unreliable. When the com-
pass signal is restored, HEADING FAIL disco

appear as stationary echoes. In the sea stablized TM
without set and driit input, the landmass can move on
the screen.
When own ship reaches a point corresponding to
75% of the radius of the display, the own ship is
automatically reset to a point oi 75% radius opposite
to the extension of the heading line passing through
the display center. Resetting can be made at any
moment before the ship reaches the limit by pressing
the [SHIFT] key. Automatic resetting is preceded by a
beep sound.

OPTIONAL EQUIPMENT, PARTS LOCATION
A.1 Performance Monitor
(Option)
A performance monitor is required for a ra-
dar installed on vessels of 300 GT and up-
ward engaged in international voyages. The
FURUNO PM-3O satisfies the requirement
covering 9410 t 50 MHz. The following de—
scribes how to use these performance moni-
tors.
The performance monitor is an independent
unit, namely, it is not interconnected with any
unit 01 the radar system except for the 100
VAC powercable. in some radars the power
cable is not routed via the power switch or
other control of the radar and the monitor is
operated as completely a separate device.
Operating the performance monitor
When Radar Interswitch RJ-7 is connected,
set it to the “straight” mode. Select PM ON
by pressing [MENU], [0]. [0], [0], [0], [5], [5],
[3], and the range scale is automatically set
to 24 nm. The radar screen will show sev-
eral arcs, opposite to the heading marker
(provided that the performance monitor is in-
stalled behind the radar antenna as is nor-
mally the case). It the radar transmitter and
receiver are in good working conditions in
as much as the original state when the moni-
tor was turned up, the innermost are should
appear at 12 nm and there should be a total
of 4 arcs.
The range of the innermost arc reduces 3
nm with every 3 dB loss of transmitted power.
Meanwhile the receiver sensitivity can be
evaluated from the number 01 visible arcs;
one are is lost every 3 dB deterioration ol
the sensitivity.

A.2 Interswitch Unit RJ-7
(Option)
The interswitching unit RJ-7 permits inde-
pendent or coordinated operation of two ra-
dar systems among FR-t 505 MARK-3
series.
5. Press the [ENTER/SELECT] key.
6. Press the [MENU] key.
1.14 Adjusting the Sensitivity
The GAIN control adjusts the sensitivity ofthe
receiver. it works in precisely the same man-
ner as the volume control of a broadcast re-
ceiver, amplifying the signals received.
The proper setting is such that the back-
ground noise is just visible on the screen. If
you set up for too little sensitivity, weak ech-
oes may be missed. On the other hand ex-
cessive sensitivity yields too much
background noise; strong targets may be
missed because of the poor contrast between
desired echoes and the background noise on
the display.
To adjust receiver sensitivity, transmit on long
range, and adjust the GAIN control so back-
ground noise is just visible on the screen.
1.15 Suppressing Sea Clutter
Echoes from waves cover the central part of
the display with random signals known as sea
clutter. The higher the waves, and the higher
the scanner above the water, the further the
clutter will extend. When sea clutter masks
the picture, suppress it by the A/C SEA con-
trol. rotate for manual adjustment, push tor
automatic adjustment.
Manual adjustment by the NC SEA
control
The NC SEA control reduces the amplifica-
tion of echoes at short ranges (where clutter
is the greatest) and progressively increases
amplification as the range increases, so am-
plification will be normal at those ranges
where there is no sea clutter.
The proper setting 01 the A/C SEA control
should be such that the clutter is broken up
into small dots, and small targets become dis~
tinguishable.
It the control is set too low, targets will be
hidden in the clutter, while it it is set too high,
both sea clutter and targets will disappear
from the display. in most cases adjust the
control until clutter has disappeared to lee-
ward. but a little is still visible windward.
1 . Confirm that the sensitivity is properly ad-
justed, and then transmit on short range.
2. Adjust the A/C SEA control so small tar-
gets are distinguishable but some clutter
remains on the display.

The NC AUTO control automatically sup-
presses sea clutter as well as rain clutter.
Push the A/C SEA control to turn on the au-
tomatic NC circuit. A/C appears at the bot-
tom left comer when the A/C circuit is on.
Turn oft the A/c AUTO ieature when its use
is not required: it can erase weak target

1.19 Measuring Bearing
Use the Electronic Bearing Lines (EBLs) to
find bearing of a target. There are two EBLs,
No.1 and No.2, which are toggled by suc-
cessive presses of the [EBL ON] key. Each
EBL is a straight dashed line extending out
from the own ship position up to the circum-
ference of the radar picture. The fine dashed
line is the No.1 EBL and the coarse dashed
one is the No.2 EBL.
1. Press the [EBL ON] key to display either
of the EBLs. Successive presses of the
[EBL ON] key toggles the active EBL be-
tween No.1, N02 and index lines (it dis-
played) and the currently active EBL
readout is circumscribed.
2. Rotate the EBL rotary control clockwise
or counterclockwise until the active EBL
bisects the target of interest, and read its
bearing at the lower-left corner of the
screen.
3. Press the [EBL OFF] key to erase each
EBL.
The EBL readout is affixed by “R" (relative) if
it is relative to own ship’s heading, or“? (true)
it it is referenced to the North, as determined
by the item CURS/EBLNFtM on the OTHER
menu.
Note: Bearing reference cannot be selected ‘ '
for NO type (no menu selection). For the IMO
type, relative bearing is selected in the HU
mode, and tme bearing in HUTB, CU. NU
and TM modes.
Each EBL carries a range marker, a short line
crossing the EBL at right angles, and its dis-
tance from the EBL origin is indicated at the
WM readout whether or not the correspond-
ing VRM ls displayed. The range marker
changes its position along the EBL with the
rotation of the WM rotary control.

1.22 Setting a Target Alarm
Zone
The target alarm feature should never be
relied upon as the sole means tor detecting
the risk of potential collision. The operator
of a ship is not relieved of the responsibility
to keep lookout for avoiding collisions,
whether or not the radar is in use.
The target alarm serves to alert the naviga-
tor to targets (ships, landmassss, etc.) en-
tering a certain area, with visual and audible
alarms.
The zone has a fixed width of 0.5 nm in the
radial direction (depth) and Is adjustable only
within 3.0 to 6.0 nm from own ship. On the
R-type, the outer and inner boundaries can
be set at any distance. On any radar type,
the sector of the zone can be set anywhere
between 0 and 360 degrees in any direction.
To set target alarm zones:
1. Press the [MENU] key.
2. Press the [3] key twice to show the TGT
ALARM menu.

1.24 Echo Averaging
The echo average feature effectively sup-
presses sea clutter. Echoes received from
stable targets such as ships appear on the
screen at almost the same position every ro-
tation of the scanner. On the other hand, un-
stable echoes such as sea clutter appear at
random positions.
To distinguish real target echoes from sea
clutter, echo average performs scan-tc-scan
correlation. Correlation is made by storing
and averaging echo signals over successive
picture frames. If an echo is solid and stable,
it is presented in its normal intensity. Sea clut-
ter is averaged over suwessive scans result-
ing in the reduced brilliance, making it easier
to discriminate real targets from sea clutter.
To properly use the echo average function, it
is recommended to first suppress sea clutter
with the A/C SEA control and then do the lol-
lowing:
1. Press the [F1] key.

Figure 1-24 Echo averaging
Echo averaging uses scan-to-scan signal cor-
relation technique based on the true motion
over the ground of each target. Thus, small
stationary targets such as buoys will be
shown while suppressing random echoes
such as sea clutter. Tme echo average is not
however effective lor picking up small targets
running at high speeds over the ground.
Echo average is inoperable when a compass
signal is not available. it you wish to use this
feature without a compass signal, consult a
FUHUNO representative.
Manual speed entry is done at the menu item
MAN SPD on the OTHER menu, which is ac-
cessed by pressing the [MENU] key followed
by the [0] key.
Do not use the Echo Average feature under
heavy pitching and rolling; loss of targets
can result.

VIDEO PLOTI'ER RP-17 (OPTION)
The Video Plotter FiP-17 is an optional circuit board which is accommodated in the display
unit of the FR-1505 MARK-3 series radars. It permits use at two memory cards: a memory
card(FlAM) for storing the operator-created radar maps, and the other is a chart card(ROM)
storing FURUNO made digital charts.
The memory card enables the operator to create radar maps more precisely than the stan-
dard supplied radar map card (150 points per map). The radar map can hold a maxium of
3,000 points. The card permanently retains the data you have entered from the radar display
or by Lat/Long positions. Own ship and other ship tracks may be stored at a selected interval.
To display Nav line, RTE and WPL sentences are necessary. WPL lD sentence received in
figure only, The data can be copied for other ships of the same shipping company.
Charts are superimposed on the radar picture without disturbing the radar observation. The
chart area is dependent on the radar range in use.
The drive for the ROM card can also drive the Electronic Fleierence Chart (ERG). The ERC is
a digital chart published bythe Japanese Hydrographic Bureau. Note it is not an ENC used Ior
ECDIS.
For details, reler to the separate manual Ior the Video Plotter PIP-17.

Alc SEA' control
For optimum range SART detection, this con-
trol should be set to the minimum. Care
should be exercised as wanted target in sea
clutter may be obscured. Note also that in
clutter conditions the first few dots of the
SART response may not be detectable, irre-
spective of the setting of the anti-clutter sea
control. In this case, the position of the SART
may be estimated by measuring 9.5 nautical
miles from the furthest dot back towards own
ship.
Some sets have automatic/manual anti-clut-
ter sea control facilities in which case the op-
erator should switch to manual.
Alc RAIN control
This should be used normally (to break up
areas of rain) when trying to detect a SAFiT
response which, being a series of clots, is not
affected by the action of the anti-clutter 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.
Some sets have automatic/manual anti-clut-
ter rain control facilities in which case the op-
erator should switch to manual.
Note: This SART information is excerpted
from IMO SN/Circ 197 Operation of Marine
Radar for SART Detection
3.4 RACON (Radar Beacon)
A racon is a radar transponder which emits
a characteristic signal when triggered by a
ship's radar (usually only the 3 centimeter
band). The signal may be emitted on the
same frequency as that of the triggering ra-
dar, in which case it is superimposed on the
ship's radar display automatically.
The recon signal appears on the PM as a
radial line originating at a point just beyond
the position of the radar beacon or as a
Morse code signal (figure below) displayed
radially from just beyond the beacon.

Notes:
1) If the 1.5 nm range is preset for
pulselength of S1 or 82, and the 3 nm
scale for $2, the echo stretch is not avail-
able on those range scales.
2) The echo stretch magnifies not only small
target pips but also returns (clutter) from
sea surface. rain and radar interference.
For this reason make sure these types of
interference have been sufficiently sup-
pressed before activating this function

3.3 SART (Search and Rescue
Transponder)
A Search and Rescue Transponder (SART)
may be triggered by any X-Band (3 cm) ra-
dar within a range of approximately 8 nm.
Each radar pulse received causes itto trans-
mit a response which is swept repetitively
across the complete radar frequency band.
When interrogated, it first sweeps rapidly (0.4
118) through the band before beginning a rela-
tively slow sweep (7.5 us) 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 inter-
rogating 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 nautical miles
will be shown.

3. RADAR OBSERVATION
3.1 General
Mlnlmum and maximum ranges
Minimum range
The minimum range is defined by the short-
est distance at which, using a scale 01 1.5 or
0.75 nm, a target having an echoing area of
10 m2 is still shown separate from the point
representing the scanner position.
It is mainly dependent on the pulselength,
scanner height, and signal processing such
as main bang suppression and digital quan-
tization. it is a good practice to use a shorter
range scale as far as it gives favorable deli-
nition or clarity of picture. The IMO Resolu-
tion A. 477 (Xll) and IEC 936 require the
minimum range to be less than 50 m. All
FURUNO radars satisly this requirement.
Maximum range
The maximum detecting range of the radar,
Hmax, varies considerably depending on sev-
eral factors such as the height of the scan-
ner above the waterline, the height of the
target above the sea, the size, shape and
material at the target, and the atmospheric
conditions.
Under normal atmospheric conditions. the
maximum range is equal to the radar hori-
zon or a little shorter. The radar horizon is
longer than the optical one by about 6% be-
cause at the dlflraction property of the radar
signal. The thax is given in the following
equation.
RW- 22 x (mi—din?)
where Hmax: radar horizon (nautical miles)
M: scanner height (m)
i121 target height (m)
Radar horizon
Optical horizon
Figure 3-1 Radar horizon
For example, if the height of the scanner
above the waterline is 9 meters and the height
of the target is 16 meters, the maximum ra-
dar range is;
RmF2.2x(/§+Vfi)=2.2x(3+4)=15.4nm
It should be noted that the detection range Is
reduced by precipitation (which absorbs the
radar signal).
x-band and S-band
ln lair weather, the above equation does not
give a signilicant difference between X- and
S-band radars. However, in heavy precipita-
tion condition, an S-band radar would have
better detection than an X-band radar.
Radar resolution
There are two important factors in radar
resolution (discrimination): bearing resolution
and range resolution.
Bearing resolution
Bearing resolution is the ability of the radar
to display as separate pips the echoes re-
ceived from two targets which are at the same
range and close together. it is proportional
to the scanner length and reciprocally pro-
portional to the wavelength. The length of the
scanner radiatorshould be chosen lora bear-
ing resolution better than 2.5” (IMO Resolu-
tion). This condition is normally satisfied with
a radiator of 1.2 m (4 it) or longer in the X-
band. The S-band radar requires a radiator
of nominal 12 feet (3.6 m) in our product
range.

The FFl-1505 MARK-3 series radar can accomodate an optional ATA (Automatic Tracking Aid)
module complying with IMO MSC.64(89) Annex 4 and IEC 60872-2. With the optional ATA
circuit board (ARP -1 7) Fitted in the display unit, the radar will automatically acquire 10 targets
coming into the acquisition area. Once a target is acquired automatically or manually it is
automatically tracked within 0.2 to 32 nm, whether inside or outside the acquisition area.

the vessel has no device which detects ship’s
leeward movement (doppler sonar 2-axis
speed log, etc.) and leeward movement is
not disregarded.
Nate 1:The ATA calculates own ship’s speed
relative to a fixed target. Therefore, when
selecting a target, a larger ground mass or a
long coast line is not suitable as a reference
target because of obscure reference point.
Note 2: Avector can be displayed forthe rel-
erence target. This can be done with REF
TGT VECT on the PLOT menu.

the [PLOT SYMBOL] key.
5. Press the [MENU] key.
Reference targets are marked with a square
symbol with a reference number (R1 , R2, R3).
2.5 Acquiring Targets
The ATA permits automatic acquisition (10
targets) plus manual acquisition (1 0 targets),
or fully manual acquisition (20 targets) within
a range of 0.2 to 32 miles. The targets are
automatically numbered and the same num-
bers are not used more than one until the
maximum capacity is reached.
Before starting the ATA, check that heading
and speed readouts at the top 01 the screen
are reasonable.
Manual acquisition
1. Place the cursor (+) on a target of inter-
est by operating the trackball.
2. Press the [PLOT SYMBOL] key.
The plot symbol changes its shape accord-
ing to the status as below. A vector appears
in about 20 antenna scans after acquisition
indicating the target’s motion trend. it the tar-
get is consistently detected for three minutes,
the plot symbol changes to a solid mark. It
acquisition fails, the target symbol blinks and
disappears shortly.

tinguishable on the display for 5 consecutive
or alternate paints out oi 10 consecutive
scans whether acquired automatically or
manually.
Targets not detected in 5 consecutive scans
become “lost targets."
Quantization
The entire picture is convened to a digital
from called “Quantified Video." Asweep range
is divided into small segments and each
range element is “1" if there is radar echo
return above a threshold level, or “0“ it there
is no return.
The digital radar signal is then analyzed by a
ship-sized echo discriminator. As the antenna
scans, itthere are 5 consecutive radar pulses
with 1’s indicating an echo presence at the
exact same range, a target “start" is initiated
Since receiver noise is random, It is not three
bang correlated. and it is filtered out and not
classified as an echo.
The same is true of radar interference. Elec-
tronic circuits track both the closet and most
distant edges of the echo. At the end oi the
scanning of the echo, the discriminator indi-
cates the measured maximum range extent
and total angular extent subtended by the
echo. If the echo is larger than a ship-sized
echo in range extent and/or angular width,
adjusted as a function of range, it is declared
to be a coastline and the closet edge is put
into memory as a map of the area.
This land outline is used to inhibit further ac-
quisition and tracking of ship sized echoes
beyond the closest coast outlinet 5 consecu-
tive scans oi coastal outline are retained in
memory to allow for signal variation. All
smaller echoes are declared to be shlp sized
and the middle of the leading edge is used to
provide precise range and bearing coordi-
nates of each echo on every scan. This
range/bearing data is matched to previous
data and analyzed from scan-to-scan for con-
sistency. When it is determined to be as con-
sistent as a real target, automatic acquisition
occurs and tracking is initiated.
Continued tracking and subsequent calcula-
tion develop the relative course and speed
of the target iust as a man would do when
plotting the relative course and speed of the
target on the scope with a grease pencil.
The true course and speed of own ship are
computed from own ship’s gyro and speed
inputs, and the resulting course and speed
at each tracked target is easily computed by
vector summing ot the relative motion with
own ship's course and speed. The resulting
true or relative vector is displayed for each
of the tracked targets. This process is up-
dated continually for each target on every

suppression lines
Performance of auto-acquisition is enhanced
by controlling the limit lines (suppression
lines) in the former series of FURUNO
AFlPAs. In the ATA, the automatic acquisi-
tion rings are used instead of the limit Ilnes.
Auto acquisition rings work as suppression
lines when viewed irom the opposite direc-
tion. The should be placed clear of a land-
mass or shoreline. The acquisition areas may
be a full 360 degree circle or sector of any
angles. They are gyro stabilized.
Qualitative description of tracking
error
The FURUNO ARPA accuracy complies with
or exceed IMO standards.
Own ship maneuvers
For slow turns there is no effect. For very high
turning rates (greater than 150°! minute, de-
pending on gyro), there is some influence on
all tracked targets which last for a minute or
two and then all tracked targets revert to full
accuracy.

When the range to the SART is reduced to
about 1 nm, 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 nm
will be interspersed with the original line of
12 dots. They will appear slightly weaker and
smaller than the original dots.

Range scale of 6 or 12 nm with normal radar

ever, this radar has a special feature which
enhances SART signals. This is done as be-

General remarks on receiving SART
SART range errors
When responses from only the 12 low tre-
quency sweeps are visible (when the SART
is at a range greater than about 1 rim), the
position at which the first dot Is displayed may
be as much as 0.64 nm beyond the true po-
sition 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 meters beyond the true position.
Radar bandwidth
This is normally matched to the radar
pulselength and is usually switched with the
range scale and the associated pulselength.
Narrow bandwidths of 3-5 MHz are used with
long pulses on long range and wide band-
widths oi 10-25 MHz with short pulses on
short ranges.
Any radar bandwidth of less than 5 MHz will
attenuate the SAFiT signal slightly, so it is
preferable to use a medium bandwidth to
ensure optimum detection oi the SART.
Radar side lobes
As the SART is approached, side lobes from
the radar scanner may show the SART re-
sponses 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 easierto detect in clut-
ter conditions and also they will confirm that
the SAFtT is near to the ship.
Gain
For maximum range SART detection the nor-
mal gain setting tor long range detection
should be used, that is, with background
noise speckle visible.
Range resolution
Range resolution Is the ability to display as
separate pips the echoes received from two
targets which are on the same bearing and
close to each other. This is determined by
pulselength only. Practically, a 0.08 microsec-
ond pulse offers the discrimination betterthan
35 m as do so with all FURUNO radars.
Test targets for determining the range and
bearing resolution are radar reflectors hav-
ing an echoing area of 10 mf.
Bearing accuracy
One of the most important features of the ra-
dar is how accurately the bearing of a target
can be measured. The accuracy of bearing
measurement basically depends on the nar-
rowness ot the radar beam. However, the
bearing is usually taken relative to the ship's
heading, and thus, proper adjustment oi the
heading line at installation is an important fac-
tor in ensuring bearing accuracy. To minimize
error when measuring the bearing of a tar-
get, out the target echo at the extreme posi-
tion on the screen by selecting a suitable
range.
Range measurement
Measurement of the range to a target is also
a very important function of the radar. Gen-
erally, there are two means of measuring
range: the fixed range rings and the variable
range marker (VRM). The fixed range rings
appear on the screen with a predetermined
interval and provide a rough estimate of the
range to atarget. The variable range marker’s
diameter is increased or decreased so that
the markertouches the inner edge of the tar-
get, allowing the operator to obtain more ac-
curate range measurements.
3.2 False Echoes
Occasionally echo signals appear on the
screen at positions where there is no target
or disappear even it there are targets. They
are, however, recognized if you understand
the reason why they are displayed. Typical
talse echoes are shown below.
Multiple echoes
Multiple echoes occur when a transmitted
pulse returns from a solid object like a large
ship, bridge, or breakwater. A second, a third
or more echoes may be observed on the dis-
play at double, triple or other multiples of the
actual range 01 the target as shown below.
Multiple reflection echoes can be reduced
and often removed by decreasing the gain
(sensitivity) or properly adjusting the NC SEA
control.

Sidelobe echoes
Every time the radar pulse is transmitted,
some radiation escapes on each side of the
beam, called ‘sidelobes.’ It a target exists
where it can be detected by the side lobes
as well as the main lobe. the side echoes
may be represented on both sides 01 the true
echo at the same range. Side lobes show
usually only on short ranges and from strong
targets. They can be reduced through care-
ful reduction of the gain or proper adjustment
of the A/C SEA control.

corrections are beneficial for increasing the
accuracy of the vector data. The correction
is best made on relative motion with true vec-
tor, watching Iandmasses, buoys, or station~
ary targets. Thus, the speed and course 01
own ship over the ground are reciprocally
calculated and compared with the relative
bearing and range to the reference target to
produce a Set and Drift. These values are
applied to all targets. If stationary objects
have vectors, the set and drift should be cor-
rected until they lose their vectors.
If own ship is equipped with a device to indi-
cate ocean current movements, the values
shown on it may be used.

2.11 Alarms
CPA/TCPA alarm
Visual and audible alarms are generated
when the predicted CPA and TCPA of any
target become less than their preset limits.
Press the [AUDIO OFF] key to acknowledge
and silence the CPA/T CPA audible alarm.
The ATA continuously monitors the predicted
range at the Closest Point oprproach (CPA)
and predicted time to CPA (T CPA) of each
tracked target to own ship.
When the predicted GPA of any target be-
comes smaller than a preset CPA alarm range
and its predicted TCPA less than a preset
TCPA alarm limit, the ATA releases an au-
dible alarm. in addition, the target plot sym-
bol changes to a triangle and flashes together
with its vector.
Provided that this feature Is used correctly, it
will help prevent the risk 01 collision by alan-
ing you to threatening targets. It is important
that GAIN, A/C SEA, A/C RAIN and other
radar controls are properly adjusted and the
ATA is set up so that it can track targets at-
fectlvely.
CPA/TCPA alarm ranges must be set up prop-
erly taking into consideration the size, ton-
nage, speed. turning performance and other
characteristics of own ship.
TAHG ET SWAP
When a tracked target near another tracked
target, the targets may be 'swapped.'
When two targets come close to each
other, one of the two can become a "lost
target." Should this happen, reacquisiticn
ol the "lost target“ is required after the two
targets have separated.

2.2 Criteria of Tracking
A target measuring 800 m or more in the ra-
dial or circumferential direction is regarded
as a Iandmass and not acquired or tracked.
Echoes smaller than 800 m are regarded as
targets to be tracked.
The FUFIUNO AFIPA ATA video processor
detects targets in midst of noise and discrimi-
nates radar echoes on the basis ottheir size.
Target whose echo measurements are
greater than those of the largest ship in range
or tangential extent are usually land and are
displayed only as normal radar video. All
smaller ship-sized echoes which are less than
this dimension are further analyzed and re-
garded as ships and displayed as small
circles superimposed over the video echo.
When a target is first displayed, it is shown
as having zero true speed but develops a
course vector as more information is col-

Acquisition and tracking
A target which is hit by 5 consecutive radar
pulses is detected as a radar echo.
Auto acquisition is not defined in paints but
in time, which should be less than 3 s of ini-
tial stage.
Manual acquisition is done by designating a
detected echo with the trackball. Automatic
acquisition is done in the acquisition areas
when a target is detected 5-7 times continu-
ously depending upon the congestion. Track-

1.46 Radar Map (RP-17 required)
A radar map is a combination of map lines
and symbols whereby the user can define
and input the navigation, route planning and
monitoring data on the radar equipment. Map
lines are navigational facility whereby the
observer can define lines to indicate chan-
nels or traffic separation schemes. Also called
nav lines. these lines can be ground stabi-
lized to stop them from drifting. (Definition In
lEC 609364 and IEC 60872-1)
In this series oi radar, a radar map may con-
tain 3,000 points of mark and line data on
one map. One map can be memorized to te-
cilitate the repeated use on the routine navi-
gation area.
The user can create a radar map on-real time
base while using the radar lor navigation or
at leisure time at anchor or while the radar is
not being used. Place of a map can be made
for any watenlvays apart from the actual own
ship location. The map data is stored on
EEROM card which is mounted on the main
processor board socket. When the optional
RP board RP-17 and RAM card are installed
in the display unit, much more data can be
created and copied to another card.

1.36 Echo Stretch, Enhanced
Video
Echo stretch
on long ranges target emoes tend to shrink
in the bearing direction, making them diffi-
cult to see. On short and medium ranges such
as 1.5, 3 and 8 nm scales, the same size
targets get smaller on screen as they ap-
proach the own ship. These are due to the
inherent property of the radiation pattern at
the antenna. To enhance target video. use
the echo stretch function. There are two
types: echo stretch 1 (E81 ) to enlarge in bear-
ing direction lor long range detection, and
echo stretch 2 (E82) to enlarge in range di-
rection on 1.5-6 nm scales.

1.34 FUNCTION Key
The FUNCTION key works similar to the au-
tomatic dialing feature on a telephone, play-
ing back control settings just as they were
registered. Instead of manually adjusting con-
trols to set up for a particular condition. for
example, navigation in a harbor. you can have
the [FUNCTION] key to do it for you.
Presetting the FUNCTION key
The radai’s internal computer otters several
navigation condition setups as outlined in the
table below. For instance, you might want to
select HBR (Harbor) as objective “FUNC1'
of the [FUNCTION] key. Then. when you se-
lect F1 with this key the radar will be instemly
set to magnify target echoes on the 1.5 nm
range or lower.
The navigation condition setup options as-
signable to the [FUNCTION] key are shown
in the table below.
Each setup option defines a combination of
several radar settings for achieving optimum
setup for a particular navigating situation.
Those involved are echo average, interfer-
ence rejector, echo stretch, noise rejector,
enhanced video, video contrast. automatic
anti-clutter.
Adjusting these features on a function key

CPA/TCPA alarm ranges must be set up prop-
erly taking into consideration the size, ton-
nage, speed, turning performance and other
characteristics of own ship.

1.25 Electronic Plotting Aid (EPA)
10 operator-selected targets can be plotted
electronically to assess their motion trend.
Five past positions can be displayed ioreach
of the plotted targets. If you enter a 6th plot
on a certain target, the oldest plot (past posi-
tion) will be erased.
A vector appears when you enter a second
plot for the target and is updated each time a
new plot is entered. The vector shows the
target motion trend based on its latest two
plots.
Target data is shown in the data display area
which shows range, bearing, course, speed,
CPA and TCPA of the last-plotted or selected
target.

Note:
Target 2 is on a collision course as the extension
at its vector goes through the own ship position.
Placing the offset EBL will help tor assessment.
TCPA is counted up to 99.9 min and beyond
that it is indicated as TCPA > 99.9 MIN.
Figure 1-25 EPA display
Note: EPA requires speed input (automatic
or manual) and a compass signal. The vec-
tor and data are updated on real time be-
tween plot entries, but do not neglect to plot
a new position over a long period of time.
Otherwise, the accuracy will be reduced. Note
that the plots will be lost when the compass
tails; start the plotting exercise again.
Plotting a target
1. Place the cursor on a target of interest by
operating the trackball.
2. Press the [PLOT SYMBOL] key. An un-
used plot symbol is marked at the cursor
position.
3. Watching the EPA time shown at the right
side at the screen, wait for at least 30
seconds. Place the cursor (+) on the tar-
get at its new location. press the [PLOT
SYMBOL] key.
The plot symbol moves to the new target
position and previous position is marked
by a small dot.
4. To acquire other targets, repeat the above
steps selecting ditferent plot symbols.
Note: if a target once plotted is not plotted
again within 12 minutes, the waming “UP-
DATE PLOT“ will appear on the upper right
margin of the screen and the plot symbol oi
the target flashes. Plotting of a target will be
ceased if the time between consecutive plots
exceeds 12 minutes. If you want to continue
plotting this target, reacquire it within one
minute. Otherwise. thetarget will be regarded
as a “Iosttarget” and its plot symbol and tar-
get data will be erased. The larger the plot-
ting interval, the Iess accurate the plotted
target data. Plotting of each target should nor-
mally be made every 3 or 6 minutes as far as
possible. You can use a Watch Alarm to warn
yourself every 3 or 6 minutes.
Within 30 seconds. you can cancel a last plot
by the [CANCEL/CLEAR] key and make a
re-emry at a different position. After 30 sec-
onds, the last entry is processed to produce
a vector.
True or relative vector, vector time
Vectors can be displayed relative to own
ship's heading (Relative) or with reference
to the North (True). This feature is available
in all presentation modes (compass must be
working correctly). The current vector mode
is indicated at the upper-right comer of the
screen.
Note: If you wish to create a target alarm
zone having a 360-degree coverage around
own ship, set point “B” in almost the same
direction (approx. 13°) as point “A' and press
the [T GT ALARM] key.
Two alarm zones can be set as described
above. To change the active alarm zones, do
steps 1 thru 4 in the above procedure. (When
both alarms are prepared the active alarm is
circumscribed.)
Acknowledging alarm
A target entering the ALARM zone produces
both visual (Ilashing) and audible (beeping)
alarms. To silence the audible alarm, press
the [TGTALARM] key shortly. ACKN replaces
IN (orOUT).
This will deactivate the audible alarm but will
not stop the flashing of the target In the tar-
get alarm zone. To reactivate the audible
alarm, press the [TGT ALARM] key again.
To silence the audible alarm, you may press
the [TGT ALARM] key. However, In this case,
the label ACKN does not appear.
Deactivatlng target alarm
Hold the [TGT ALARM] key depressed for at
least 5 seconds.
Note: The target alarm is given to targets hav-
ing a certain level 01 echo strength. This level
doesnot always imply a landmass. reef, ships
or other surface objects but can mean returns
from the sea surface or precipitation. Prop-
erly adjust the GAIN, AIC SEA, and NC RAIN
controls to reduce noise to avoid generation
of the guard alarm against false targets.
Inward and outward target alarms
On the R-type, an inward or outward target
alarm can be selected on the TGT ALARM
menu. On the IMO type, only the inward
guard alarm is available. The inward guard
alarm generates visual and audible warnings
when a target enters the target alarm zone
lrcm any direction. The outward target alarm
is produced when a target leaves the target
alarm zone. (This is not a target alarm by defi-
nition but some users line this feature valu-
able.)

1.23 Off-centering (shift)
Own ship position, or sweep origin, can be
displaced to expand the view field without
switching to a larger range scale. The sweep
origin can be off-centered to a point speci-
fied by the cursor, up to 75% of the range in
use in any direction.
This feature is not available on the longest
range scale or in the true motion mode. The
number of range rings increases keeping the
original range intervals unchanged.
To oft center the radar picture:
1. Place the cursor at a position where you
wish to move the sweep origin by operat-
ing the trackball.
2. Press the [SHIFT/ZOOM] key with a
touch-and-release action. Then, the
sweep origin is olf-oemered to the cursor
position. However, the heading line is left
in the same position.

1.20 Collision Assessment by
the Offset EBL
The origin of the EBL can be placed any-
where with the trackball to enable measure-
ment of range and bearing between any
targets. This lunction Is also useful for as-
sessment of the potential risk at collision.
To assess possibility ol collision:
1. Press the [EBL ON] key to display or ac-
tivate an EBL (No.1 or No. 2).
2. Place the cursor (+) on a target of inter-
est (A in the illustrated example) by oper-
ating the trackball.
3. Press the [EBL OFFSET] key, and the ori-
gin of the active EBL shifts to the cursor
position. Press the (EBL OFFSET] key
again to anchor the EBL origin.
4. After waiting for a few minutes (at least 3
minutes), operate the EBL rotary oontrol
until the EBL bisects the target at the new
position (A’). The EBL readout shows the
target ship's course, which may be true
or relative depending on the settings on
the OTHER menu.
it relative motion is selected, it is also pos-
sible to read CPA (Closest Point at Ap-
proach) by using a VRM as shown below
(Figure (a)). It the EBL passes through
the sweep origin (awn ship) as illustrated
(Figure (b)), the target ship is on a colli~
sion course.

1.16 Suppressing Precipitation
Clutter
The vertical beamwidth of the scanner is de-
signed to sea surface targets even when the
ship is rolling. However, by this design the
unit will also detect rain clutter (rain, snow,
or hail) in the same manner as normal tar-
gets. Figure 1-11 shows the appearance of
rain clutter on the display.
The NC RAIN control adjusts the receiver
sensitivity as the A/C SEA control does but
rather in a Icngertime period (longer range).
Clockwise rotation of this control increases
the anti-clutter effect.

1 .17 Interference Rejector
Mutual radar interference may occur in the
vicinity of another shipbome radar operating
in the same frequency band (9 GHz). It is
seen on the screen as a number of bright
spikes either in irregular patterns or in the
form of usually curved spoke-like dotted lines
extending from the center to the edge of the
picture. This type of interference can be re-
duced by activating the interference reiector
circuit.
The interference reiector is a kind of signal
correlation circuit. It compares the received
signals over successive transmissions and
suppresses randomly occurring signals.
There are three levels of interference rejec-
tion depending on the number ol transmis-
alone that are correlated. These are indicated
by the legends IFI1, IR2 and IRS at the up-
per-left position of the screen

1.18 Measuring the Range
Measuring range by the fixed range
rings
Use the fixed range rings to obtain a rough
estimate of the range to a target. They are
concentric solid circles about own ship, orthe
sweep origin. The number 01 rings is auto-
matically detennlned by the selected range
scale and their interval is displayed at the up-
per-left position of the screen.
