MDC-5200/5500 Series Break in procedure of stored radar

0093155002-00 vii

Break in procedure of stored radar

Following procedure is recommended for “Break In” of the stored radar.

Otherwise the radar sometimes exhibits unstable transmitting operation

such as arcing at its initial operation after long period of storage and make

the operation more difficult.

1. Extend preheat time as long as possible (preferably 20 to 30

minutes).

2. Set the pulse width to the shortest one and start the operation.

When the operation in the shortest pulse is stable then go to

operation in longer pulse and repeat the similar step until the

operation reaches to the final pulse condition.

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.

Selection of MAN GAIN and AUTO GAIN

By GAIN knob

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

By trackball/joystick

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

of the display.

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

AUTO adjustment of GAIN

When AUTO GAIN is set, [GAIN] is adjusted automatically.

Note: AUTO GAIN may remove weak target echoes, or too much sea clutter may be on the display, turn

GAIN knob clockwise or counterclockwise to adjust AUTO GAIN effectively.

If not setup properly, adjust AUTO GAIN settings by referring to 4.4.3 Setup GAIN MIN and MAX

mode of Installation manual.

0093155002-00 2-10

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.

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.

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.

• 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/joystick

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.

0093155002-00 2-11

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 4.4.3 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.

2.8 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.

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

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

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.

• The performance of radar detection range is degraded by rain as shown in the figure below.

The details of the figure (An example of 6 NM range)

A target which was able to observe at 6 NM (Original range of first detection), can only be detected at

the range (Reduced Range of First Detection) shown below in rain condition.

4 mm/h rain (short pulse): approx. 5.6 NM 4 mm/h rain (long pulse): approx. 1.5 NM

16 mm/h rain (short pulse): approx. 3.9 NM 16 mm/h rain (long pulse): approx. 0.5 NM

2.10 Select Display Mode

The display mode is a combination of the bearing indication and the target motion indication.

The bearing is indicated in three ways: HUP, CUP and NUP.

The target motion is indicated in two ways: RM and TM.

1 Move cursor on the DISPLAY MODE display, and press ENT key.

The display changes in following order by pressing ENT key. Current display mode is displayed at

the upper left of the display.

Note: Display mode can be changed directly to press MODE key. (MDC-5500 series only)

For H UP (Head up mode)

Heading line is always oriented toward the top of the display.

This mode is based on the bow of the ship and is suitable to monitor targets because targets are seen

as they are in navigating own ship.

When heading signal is connected, H UP works by stabilized mode. (STAB H UP)

Note:

・This is a presentation mode stabilized in azimuth with fixed origin in which the radar image is oriented

“up” toward the top of the bearing scale.

・Radar echoes and tracked targets are shown at their measured distances and moving in a direction

relative to own ship’s heading.

・The heading line points from the own ship to the top of the bearing scale showing own ship’s heading

in true bearing mode.

For C UP (Course up mode)

When choosing Course up mode, current heading becomes the course at the top of the display and a

moving heading line indicates actual.

This mode is used to navigate towards a specified course.

It easily shows any deviation of own ship from the specified course.

Note:

・This is an azimuth-stabilized presentation in which the bearing scale can be oriented so that own

ship’s course on the bearing scale is vertically above the own ship.

・The heading line points from the own ship to own ship’s referenced heading on the bearing scale.

・If own ship’s heading differs from the course, then the heading line does not point vertically upwards

from the own ship until the bearing scale is reset (manually or automatically) to reflect the course

alteration.

For N UP (North up mode)

This mode always keeps true north at the top of the display.

A north oriented representation makes it easy to reference with a chart.

Note:

・ This is an azimuth-stabilized presentation in which north on the bearing scale remains fixed vertically

above the own ship.

・ The heading line points from the own ship to own ship’s referenced heading on the bearing scale.

・ The true bearing of any target on the display is measured from north.

Center of display

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.

True motion (TM): The antenna position on the display moves according to its speed and tidal current.

Stationary targets are fixed on the display. This mode is useful to monitor your

position with respect to the fixed targets such as land.

ground information from satellite navigation system. Accordingly course and speed indication at the

upper right side of the display becomes COG/SOG. Speed in water sensor may be affected by current

and stable operation may be spoiled.

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

 If failure of 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 XXX.X in orange

color.

Chapter 2 Radar Basic Operation MDC-5200/5500 Series

0093155002-00 2-36

Relative display (R)

The target trail is displayed as result of sum of vector (course and speed) of the target ship and your

ship. When your ship is on the projected course of this trail, it shows that a collision may occur in future.

This display is useful to help detect a dangerous situation.

Target 1, whose trail is overlapping the EBL, is a dangerous target while the Target 2 is not. If trail

setting is six minutes, and if the trail length is equal to the distance between the antenna position and

Target 1, then the collision will occur after six minutes.

True display (T)

This mode displays the trail of the moving target over a specified time interval independently from own

ship's movement.

This mode is used to monitor the bearing and speed of the target.

No trails of fixed targets such as land are shown using this display.

The amount of movement of all ships, own ship, Target 1 and Target 2 are drawn as trails.

The land does not move, so its trail is not shown.

method. Three types of 1, 2 and 3 are available.

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

1 Move the cursor to OFF, C1, C2, C3, A1 or A2 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, C2, C3, A1 and A2, 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.

Note:

• For confirmation of an image that may be hidden between the waves and the image of a fast ship that

appears at a different position for each scan, the image may be displayed weaker than the actual one.

Therefore, when fast moving target on the display, select [PROCESS] OFF.

• For operation of GAIN, SEA and RAIN, it may take some time before it becomes effective. Take

enough time for the operation, or operate again after [PROCESS] has been once off.

• Echo process mode requires heading signal, echo process mode turns into OFF if heading signal is

unavailable.

2.24 Echo expansion

This function is to enlarge an image in the direction of distance/bearing.

Small ships and remote targets can be enlarged to be easier to see.

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

1 Move the cursor to set value window of OFF, 1, 2, 3 or 4 of [EXPANSION] at the upper right part

of the display.

Press ENT key repeatedly until the desired choice appears.

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

enhance effect.

Note: The enlargement of targets has effect on all echoes. So, a large target such as land is also

enlarged. Consequently, land and a small target may sometimes be seen as a single target. Pay

attention to that.

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.
