Features
• TARGET ANALYZER* function displays targets which are moving and getting close to own ship
in red, other targets in green and rain clutter in blue. Speed analyzing range is ±50 kn.
* Requires a GPS sensor. When you change the setting of [Target Analyzer Mode] to [Rain],
rain clutter is displayed.
• AUTO TARGET ACQUIRE function automatically acquires only the targets which are moving
and getting close to own ship within the range of 3 NM by Doppler calculation. Automatic Dop-
pler function will be activated when there is a target which approaches own ship with a speed
of over 3 kn.
Note: The judged speed of target is dependent on its vector towards own ship.
• The azimuth resolution can be enhanced to as high as twice with using the RezBoost function.
Note 1: RezBoost function reflects the settings of [Antenna Length] which are introduced in
page 17 and page 19.
