• Video processing performs correlation processing for each scan.
• Video processing suppresses random undesired clutter and displays targets only.
• Accurate true bearing signals and speed signals are necessary.
• In SRM/TM/CTM mode, high processing precision can be achieved since processing is performed in
true motion.
• In RM mode, processing precision deteriorates due to the moving or traversing of own ship since
processing is performed in relative motion.
• When a target moves at a high speed and "PROC1" or "PROC2" is used, the image may be blurred or
disappear. In this case, set the processing to "OFF" or use "PROC3".
• Operation characteristics of "PROC1" to "PROC3" are as follows:
OFF : Does not perform correlation processing between scans.
At monitoring a near range such as within a bay, monitoring a target moving at a
high speed, or when a true bearing sensor is not connected.
PROC1 : Suppresses general undesired clutter and displays targets in natural gradation.
PROC2 : Suppresses random undesired clutter and displays a target by emphasizing it.
Use this processing for detecting small targets hidden by undesired clutter.
PROC3 : Displays unstable targets of low detection probability.
Use this processing when searching for small targets such as radio buoy in an area
free from sea clutter.

• Eliminates the interference by radio waves transmitted by other radar equipment.
• The interference elimination effect increases as the number increases such as IR1 ➝ IR2 ➝ IR3,
however, the sensitivity deteriorates.
• Sensitivity deterioration can be prevented by selecting processing of as smaller number as possible.
• By pressing the [BRILL] control, the transmission repetition frequency can be changed sensitively.
Interference waves can be eliminated effectively by using this function concurrently.
• The interference wave elimination circuit suppresses transceiver noise also. By increasing the
processing number, the noise displayed can be reduced. When the maximum sensitivity is required,
adjust by turning the [GAIN] control clockwise until a required noise level is displayed.
