PROCESS
This feature allows the operator to detect a weak signal target or to
detect a target in the sea clutter.
Selecting “OFF” is no video processing. “PROCESS1” is used to
detect a weak echo. “PROCESS2” and “PROCESS3” are used to scan
correlation mode for use to detect a target in the sea clutter.
“PROCESS3” is more effective than “PROCESS2” but response is
slow.
•Select “PROCESS” in RADAR SETTING menu and push the
Joystick
to display the “PROCESS” pull-down menu. Select setting
by
Joystick
up or down and push
Joystick
.
Note:
•When PROCESS2 or PROCESS3 is used, an object moving with a high
speed is displayed dimly.
“PROCESS” is a very useful feature in the North stabilized or
Course stabilized heading mode.
Note:
•Notice that when “PROCESS” is used, a target that is moving with a
relatively higher velocity than that of your own ship may provide weaker
echoes than actual ones in the display or may provide no echoes of the
target itself.
TRAILS
This feature allows the operator to see the past history of target
movement or behind the moving targets. Selecting “OFF” is no trails.
The numerical selections, 0.5, 1, 3, and 6, represent the length of the
“trail time” in minutes. For example, if 3 minutes is selected as the
interval, the trail presents the last 3 minutes of the target movement.
This provides a visual indication of a targets relative speed and course.
“CONTINUOUS” provides a continuous trail.
If range scale or bearing mode is changed, or offset display position
by the offset function, or changed display mode “RADAR” full to
“RADAR/CHART”, the trails will be cleared and new trails will be
redrawn to the screen.
The trails are drawn for anything that move on screen, including
sea gulls, sea clutter, buoys, lobsterpots, and shoreline. In general, it is
better to use the trails feature away from harbor and the shoreline to
avoid a cluttered display and to concentrate on trails of target vessels.
If own vessel changes the course all trails are influenced in HUP
mode, it is better to use the trail feature in NUP mode or CUP mode.
•Select the “TRAILS” in RADAR SETTING menu and push the
Joystick
, the “TRAILS” pull-down menu is displayed. Select settings
by
Joystick
up or down and push
