3.3.20 Displaying Video Processing Screen
● If you'll watch the RADAR BECON and the SART, Set process as follows
PROCESS OFF
● If you'll use this function on RM mode, sellect NORTH-UP bearing or COURSE-UP bearing.
This function can't be used on RM mode selected HEAD-UP.
Unnecessary targets are reduced to enhance the intended target(s).
Procedures
1. Press the
MAIN
MENU
key to open the MAIN MENU.
2. Press the
5
switch to select "PROCESS".
3. Press the
5
switch to select "PROC1", "PROC2" or "PROC3".
Selecting "OFF" returns the video to the normal display.
4. Press the
ENT
key to confirm the setting.
Exit
5. Press the
MAIN
MENU
key.
Motion of Video Processing
• 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.
