Chapter 1. Overview
1.1 Function
This equipment is a small-sized raster smayning Radar, composed of OpenArray
type transceiver with 6 KW Transmitting power and 10.4 inch color TFT LCD
monitor.
This radar complies with the regulation of frequency law.
1.2 Feature
Antenna Unit
It emits the miscrowave toward targets by 4(four)-step pulse widths according
to the radar scale and transfers the image signals to the monitor that are made
by converting the reflected signals to 2(two)-step receiver band.
Transmission Output: 6KW
Max. Range : 72NM
Display Unit
SMR-7200 monitor is designed to receive the input signal from Antenna and
to display at the optimum conditions on the TFT LCD screen, based on the
SAMYUNG② be②③ digi③al ②ignaling ③echnology.
10.4  colo① TFT LCD, High Re②ol④③ion of 640 X 480
One-touch keys dedicated to every function
10 (ten)-step LCD brightness adjustments
The input of the external navigational devices such as Gyro or NMEA 0183 enables it
to display the own ship position and the destination

26
3.3.2.1 STC Curve
The following drawings show the curve between Distance to Gain
shown as the following drawings.
You must set the figures considering the reflected wave on surface of
the sea ②③a③④② ca④②ed by an③ennas installation location.
On average, antenna is installed at the height of 5m, when waves
height is at 1m, the setted value must be at Curve 1.
2~4, is when wave height at 2~4m, where reflected wave on surface
of the sea is severe.
If antennas at height of 10m and wave at 1m, the curve must be set
as 2.
3.3.3 Tuning Control
Please refer to [3.1.2 Tuning Control].

27
3.3.4 Gain control
Turn gain key.
When you turn key left, decreases the gain, when you turn right,
increases the gain.
The optimum gain
Is when the targets ECHO display is at its maximum size, and when close by
targets are not touching on ECHO display
감도가 낮아 영상이 작다. 감도가 최적이다. 감도가 높아 2개의
영상이 붙었다.
Auto gain setting
When you push the switch in the gain volume, it will be displayed AUTO in
the bottom centre of the screen, it will be displayed GAIN-A in the right
bottom corner of the screen.
This function adjusts the gain at its optimum level, however may be affected
by environment.
ATTENTION
※It should be always observed by adjusting the optimum conditions.
※If the gain is too low, the targets may not be displayed.
※If too high, it may be an obstade in observation due to the noise increase on the display.

3.3.5 In order to remove the interference of rain/snow
!
Under heavy rain/snow, the target may be difficult to analyze since ECHO
(Rain Clutter) caused by rain and snow may be displayed.
Turn Rain CL volume right to remove the echo image by snow and rain.
Reflected wave of rain/snow Removed rain/snow
(Target is restricted, too.)
Auto setting rain/snow
When you push the switch in the volume for removal rain/snow, AUTOwill
be displayed in Rain CL in the bottom center of the screen, and RAIN-A will
show on the bottom right corner of the display
This function is only to use under circumstances where the user wants to
automatically remove the snow/rain. Hence do not use this function if not
required as it will make target smaller than usual.
※Too much adjustment of rain/snow removal will restrain the target of shipsor
hazards as well as any images by rain/snow. This can be the cause of image
analysis.
※In case of use of rain/snow removal, the optimum conditions shoud alwaysset
up..
ATTENTION

29
3.3.6 To remove the interference of Sea Level Wave caused by the Sea Wave
!
When the wave becomes high due to heavy wind, the ECHO(Sea clutter)
due to the wave is displayed on the screen, then it will be difficult to detect
the image of the target.
Turn Sea Clutter key to the right to remove the echo image by wave.
The status that shows Sea Level Reflection The status that shows Sea Level Reflection
is strong due to Wave. is being suppressed.
(The target is also suppressed)
Auto Sea Clutter removal setting
When you switch on Sea Clutter removeAUTOwill show in the
Centre of bottom of screen, and SEA-Awill show in the bottom right corner
of the screen.
This function automatically sets the optimum display, however it is not
necessary to set it when theres no need to remove the Sea Clutter as the target will
be shown smaller than usual.
ATTENTION
※If you set the removal function of Sea Level Wave up to removal of all Sea Level
Reflection at short distance, it causes intereference in detecting images due to the
target of vessel and dangerous things as well as the wave images being suppressed.
※When you use the removal function of Sea Level Wave, you make sure it should be the
optimistic set of suppression
