Sea clutter
Sea clutter is used to filter the effect of random echo returns from
waves or rough water near the vessel.
When you increase Sea clutter, filtering the on-screen clutter caused
by the echoes of waves is reduced.
The system includes predefined Sea clutter settings for harbor and
offshore conditions, in addition to the manual mode where you can
adjust the settings. You select Sea clutter modes from the menu.
You can only adjust the Sea clutter value in manual mode.
Auto Sea Offset
(Halo Radar only)
To allow fine tuning of the Sea control while in Auto mode (Auto
uses directional adaptive clutter rejection), the Auto setting may be
offset.
Rain clutter
Rain clutter is used to reduce the effect of rain, snow or other
weather conditions on the radar image.
The value should not be increased too much as this may filter out
real targets.
Advanced radar options
Noise Rejection
(Broadband 4G and Halo radar only)
The Noise Rejection control sets the amount of noise filtering
applied by the radar. Target sensitivity is increased at longer ranges
when this control is set to Low or High, but does cause some loss of
target discrimination.
Tip: To get maximum range performance from Broadband 4G
Radar, transmit on one range only, set the Noise Reject control to
High and the threshold as low as possible. The default is 30% for less
clutter on the screen. If OFF is selected for the GO XSE, the range
performance is about equal to 3G radar. In some areas where
extreme high interference may exist, try OFF for best radar image.
