electromagnetic wave. It may cause harmful effect for human body due to

its continuous radiation. As International regulation says, electromagnetic

waves less than 100 watt/m2 does not have a harmful effect on human

bodies, but some kind of medical devices such as heart pacemakers are

sensitive even under the low energy electromagnetic wave. Any personnel

with such a device should keep away from the electromagnetic wave

generating position at all times.

Mise en garde relative aux perturbations électromagnétiques produites

par les radars de navire

L'antenne & l’émetteur des radars de navire ont un rayonnement d’ondes

électromagnétique de haute intensité. Ceci peut causer des effets nocifs pour le

corps humain en raison de son rayonnement continu. Comme la réglementation

internationale le spécifie, les ondes électromagnétiques à moins de 100 watt/m

n'ont pas un effet néfaste sur le corps humain, mais certains types d’appareils

médicaux tels que les stimulateurs cardiaques peuvent être affectes même par des

ondes électromagnétiques de faible énergie. Tout membre du personnel avec un tel

dispositif devrait se tenir à l'écart des générateurs d'ondes électromagnétiques en

tout temps.

2.4 Tuning method

The transmitting and receiving frequency of this radar may become detuned by environmental

changes.

This result in “detuning” of the gain and the same echo images may show weaker, even if the setup is

the same as before.

Tuning method can be changed directly in the upper right of the display, with trackball and ENT key,

without using menu function.

Tuning menu operation method, refer to 4.2.1 Tune adjustment of Installation manual.

Change MAN (manual) and AUTO

Move cursor to the MAN or AUTO box (whichever is shown) of tune indicator at upper right of the

display using trackball and press ENT key.

Optimized value setup method

Adjustment shall be performed based on stable echo object such as from land. (Land is used in

following explanation.)

2.6 Adjust receiver gain (GAIN)

It is recommended to adjust [GAIN] in the upper right side of the display to have the evenly scattered

vague background noise with low intensity in the PPI.

Lower than required [GAIN] may result in missing small vessels and buoys.

Higher [GAIN] than required may result in difficult discrimination between small ships and densely

displayed high level background noise.

Under some situation, desired target object may be masked by side lobe of antenna directivity or false

echo by multi path.

Lower [GAIN] until masked target echo can be recognized outside of the area where 2.7 “Reject sea

clutter (anti-SEA)” is effective.

However since lower [GAIN] tends to lose weak target echo, try to return the [GAIN] to original position

each time [GAIN] is changed to maintain target recognition. In the short distance area where anti-SEA

is effective, recognize target by adjusting MAN SEA.

When suppressing RAIN clutter (rain & snow), adjust GAIN knob and RAIN knob side by side.

[GAIN] state is displaying in the upper right of the display.

2.7 Reject sea clutter (anti-SEA)

MAN (manual) SEA and AUTO (automatic) SEA are provided for

anti-SEA function. On the rough sea, SEA clutter noise appears

around antenna position (center spot), and short distant targets

are masked and not recognizable. In that case, anti-SEA function

suppresses sea clutter noise and reveals masked target echoes.

Recommended adjustment of anti-SEA is to adjust to make

echoes from sea clutter vaguely displayed by low (weak) level.

SEA clutter at center

After Adjusted MAN SEA

If target echoes are masked by excessive false echoes within anti-SEA effective area, then adjust MAN

SEA to confirm it. Excessive anti-SEA may lose echoes from small ships and buoys. So, return to

appropriate anti-SEA level for normal use.

Note:

• Small targets become harder to detect when [SEA] is used together with [RAIN]. Therefore, please

adjust them carefully.

If anti-SEA level is too high to show sea clutter noise, short

distance gain is over suppressed and it may result in loss of

targets like buoys and small ships.

On the other hand, if anti-SEA level is too low, clutter noise around

antenna position (center spot) is displayed by high intensity level

and it makes difficult to discriminate small ships and buoys from

sea clutter.

Anti-SEA is effective to suppress false echoes and ground clutter

in short distance. However adjustment of GAIN should be used

beyond effective coverage of anti-SEA.

• The echo process (refer to 2.23 Echo process) is useful to reject sea clutter. Be careful, when the

echo process is active, high-speed targets are harder to detect than stationary ones.

Selection of MAN SEA and AUTO SEA

By SEA knob

When the SEA knob is pressed, AUTO SEA and MAN SEA change alternately.

By trackball

1 Move cursor on the MAN or AUTO display (whichever is shown) at right side of [SEA] on the top of

the display.

2 Press ENT key to display AUTO or MAN as appropriate.

AUTO adjustment of SEA

When AUTO SEA is set, anti-SEA is adjusted automatically.

Note: AUTO SEA may erase weak target echoes. If excessive sea clutter erasing or too much clutter is

observed, turn SEA knob clockwise or counterclockwise to adjust AUTO SEA effectively.

If not setup properly, adjust it by referring to 4.5.3 Setup GAIN MIN and MAX mode of Installation

manual.

In case there are strong echo targets such as in the harbor or canal, anti-SEA tends to suppress

excessively, use MAN SEA in that case.

Manual adjustment of SEA

When MAN SEA is selected, anti-SEA can be adjusted manually.

By using SEA knob, suppress this effect and make targets seen easier.

[SEA] state is displayed in the upper right of the display.

1 Turn SEA knob clockwise to increase anti-sea clutter effect.

Turn SEA knob counterclockwise to decrease anti-sea clutter effect.

2 Turn SEA knob clockwise until even low (weak) SEA clutter is displayed by observing the display.

3 Adjust SEA knob from time to time to get low (weak) SEA clutter on the display as intensity of sea

clutter changes as time passes.

Low

Note:

• When waves do not affect the result, turn the knob fully counterclockwise.

• This function reduces gain in closest ranges. Too much sea clutter may result in actual targets being

lost.

• Manual SEA user keep watching and adjusting SEA with changing conditions.

• If SEA and anti-RAIN are used in combination, then small targets will be less visible.

2.8 Reject rain/snow clutter (anti-RAIN)

In rain or snow, targets become hard to be seen as a result of

unwanted weather reflection.

Rain or snow image appears as a large target echo with

surrounding mid gradation rim as shown in the picture.

Anti-RAIN is available MAN and CFAR.

Adjustment of MAN (manual) and CFAR (Constant False Alarm

Rate) by turning RAIN knob suppresses clutter, and helps to see

targets clearly.

MAN is effective for suppression of rain and snow.

Rain clutter

[RAIN MODE] can be changed directly in the upper right of the display without using menu function.

CFAR is effective for suppression of sea, rain and snow clutter.

Note:

• Small target becomes harder to detect when [RAIN] is used together with [SEA]. Therefore, please

adjust them carefully.

• The echo process (refer to 2.23 Echo process) is useful to reject rain clutter. Be careful, when the

echo process is active, high-speed targets are harder to detect than stationary ones.

For relative motion (RM) and true motion (TM)

Relative motion fixes your antenna position at the center of the display, and indicates the motion of

targets that surround your antenna position.

Your antenna position is displayed at the center. So, while the ship is moving, the fixed targets such as

the land also continue to move.

True motion indicates the motion of the target with respect to the specified bearing.

Fixed targets that do not move in any direction stay on the display, and all the moving targets move on

the display.

Note: The heading always continues to move. So, no true motion TM is available for H UP.

Relative motion (RM): The antenna position is fixed and the other surrounding targets move on the

display.

This is useful to monitor the surrounding situation with respect to own ship’s

position.

2.11 Ground and Sea stabilization

STAB MODE is a function to select speed for movement calculation for True trail, TT (ARPA), Past

position and True motion (TM).

SEA: Stabilization mode using speed over water.

GND: Stabilization mode using speed over ground.

[STAB MODE] can be changed directly at the upper left of the display, by cursor and ENT key.

When SDME or EPFS is not available for any reason, it is possible to get the speed over ground by

setting reference target.

Refer to 4.3 TT (ARPA) “Reference target acquisition”.

SEA (Sea stabilization)

SEA stabilization uses CTW (course through water) and STW (speed through water) referenced to

water. Accordingly course and speed indication at the upper right of the display becomes CTW/STW.

 STW is relative speed of the ship against water surface in the heading direction.

 Information from SDME (speed and distance measuring equipment) like LOG is inputted by serial

data (VBW or VHW).

 Single axis water log indicated as LOG on the display cannot detect the effect of leeway.

 When speed information is interrupted for 30 seconds from SDME for any reason or VBW water

status flag is invalid, then the numerical indication of CTW/STW becomes XXX.X in orange color.

In this case, speed can be entered manually.

5 Press ENT key to save the input.

GND (Ground stabilization)

GND stabilization uses COG (course over ground) and SOG (speed over ground) referenced to the

ground. Accordingly course and speed indication at the upper right side of the display becomes

COG/SOG.

 SOG is the absolute speed of the ship with reference to the land.

 Two-dimensional GND SDME device like dual axis LOG and EPFS (electronic position fixing

system) provide information for serial input.

 If both serial sentence data of VTG (EPFS) and VBW (SDME) are available, then VBW takes

priority.

 If failure of EPFS or SDME interrupts the speed information for 30 seconds or if the ground status

flag or VTG indicator flag is invalid, then the numerical indication of COG/SOG becomes XXXX in

orange color.

 If SDME or EPFS is not usable due to failure or any other reason, then COG/SOG can be obtained

by setting Reference target.

Refer to 4.3 TT (ARPA) “Reference target acquisition”.

Note: IMO Resolution A.823 (19) ARPAs requires connection to water speed LOG.

In addition, VTG by EPFS or VBW by dual axis LOG should comply with requirements of IMO

Resolution MSC96 (72).

method. Two types of C1 and C2 are available.

[PROCESS] mode can be changed directly at the upper right of the display using trackball.

1 Move the cursor to OFF, C1 or C2 of [PROCESS] at the upper right part of the display.

Press ENT key repeatedly until the desired choice appears.

Correlation image echo process

At setup value of C1 or C2, correlation images are averaged.

When there is a stable image such as a ship among sporadic images such as sea clutter, the sea

clutter is reduced by averaging to leave the stable image.

Due to the averaging process, even though stable strong images appeared just after transmission, they

are displayed weaker and gradually turn into strong images.

2.25 Interference rejection (IR)

This feature is used to reject interference from other radars.

Radar transmissions on same frequency band can cause interference noise on the display depending

on its transmitted power. This noise pattern appearance varies case by case, but is usually spiral shape

or like the spokes of a wheel in shape. This function can reduce interference effect.

[IR] can be changed directly at the upper right of the display.

[IR] is also effective to reduce second echo phenomenon.

1 Move the cursor to set value window of [IR] at the upper right part of the display.

Press ENT key repeatedly until desired value appears.

Note:

• The setting value can be selected from “OFF, 1, 2, and 3” and the larger value applies stronger

interference rejection effect.

• Too much removal effect may also remove small targets. Pay attention to that.

2.26 Video contrast

This is a function to change the relation between the strength of returned echo and their display

gradation.

At VID 1, the difference of signals strength between strong echo and weak echo becomes larger. As

the numerical figure becomes larger in VID 2, VID 3, VID 4, and VID 5 the difference in signal strength

becomes smaller.

[VID] can be changed directly at the upper right of the display.

1 Move cursor to 1, 2, 3, 4 or 5 of [VID] at the upper right part of the display.

Press ENT key repeatedly until desired value appears.

When the difference of signal strength is small, images becomes sharper.

However, signal strength from small ships and buoys is weak, and the difference between clutter and

them is not large enough.

Therefore, it is necessary to display clutter which may blend together with small ships and buoys.

2.30 Receiving Radar Beacons, SART and Radar Enhancer

The X-band radar system is required to be capable of receiving signals emitted from a Radar Beacon,

SART (Search and Rescue Transponder) and Radar enhancer. To receive those signals by the radar

system, use the following procedures.

1 Press MENU key to display “Menu”.

Select [ECHO] => [SART] => [ON], and press ENT key.

2 Radar functions are set with following settings.

Range scale: 12 NM

Pulse width: L2

PROCESS: OFF

Interference Rejection: OFF

Performance Monitor: OFF

3 In case the radar picture is obscured with too many signals, reduce gain for better observation.

4 When own ship approaches the transmitting Radar Beacon or SART, the echoes will become

blurred in an arc. For better observation of those signals, adjust the Gain, SEA and RAIN controls,

as appropriate.

5 [ECHO] => [SART] => [OFF], and press ENT key, the setting of above 3 is restored.

About SART

According to the GMDSS (Global Maritime Distress and Safety Systems) requirement, the IMO/SOLAS

class ships must be equipped with a SART. When a ship is in distress, a signal will be automatically

emitted from the SART so that other ships and/or aircrafts can identify its location. When your ship

equipped with a X-band radar comes within 8 NM of a ship in distress, the SART picks up the radar

signal and responds to it. The signal consists of 12 sweeps and is emitted in the frequency range of 9.2

GHz through to 9.5 GHz. The SART has two sweep times that switch from slow sweep (7.5μs) to fast

sweep (0.4μs) and vice versa, according to the distance. When the radar receives this signal, a line of

12 dots, which is equally spaced at about 0.64 NM, appears on the display. The nearest blip of the

SART indicates the location of the ship in distress. When your ship comes within 1 NM to the SART, a

fast sweep signal is displayed on the radar and a thin line connects the 12 blips.

0093169006-05E 2-42

MDC-7000P/7900P Series Chapter 2 Radar Basic Operation

Actual location of the ship carrying the SART

If your ship is located at 1 NM or more away from the SART, the position at which the first echo is

displayed is 0.64 NM behind the actual SART position when the 12 SART echoes are identified. If your

ship comes within 1 NM from the SART, the fast sweep signal is indicated. The position of this echo is

displayed 150 m beyond the actual SART position.
