Fast scan

(Broadband Radar only).
Sets the speed of the radar antenna rotation. This option gives faster
target updates.
Note:
Ú Maximum speed may not be achieved depending on
the radar Settings, Mode, and Range selected. The radar will
only rotate as fast as the current control settings allow.

Sea State

Set the Sea State control according to current sea conditions for
best sea clutter rejection.
Target boost
(3G and 4G Broadband, and Pulse Radar only)
The target boost control increases pulse length or reduces radar
bandwidth to make targets appear larger in range and increase
radar sensitivity.
