Advanced radar options
Radar threshold
The threshold sets required signal strength for the lowest radar
signals. Radar returns below this limit are filtered and are not
displayed.
Default value: 30%.
Target expansion
Target expansion overrides and increases the default radar pulse
length, providing larger target returns.
Rejecting radar interference
Interference could be caused by radar signals from other radar units
operating in the same frequency band.
A high setting reduces the interference from other radars.
In order not to miss weak targets, the interference rejection should
be set to low when no interference exists.
STC curve
(Broadband Radar™ only).
The STC (Sensitivity Time Control) controls the sensitivity of the
radar signal close to your vessel. It compensates for distance to the
radar object, making returns from equal sized objects appear with
the same size on the radar image.
