8.11 Radar: Gain, Rain clutter, Sea clutter
adjustment
You can improve your Radar display to reduce the effects of sea
clutter, rain clutter, and interference from other radars.
You can reduce false echoes by changing the sensitivity with the
gain setting.
Multiple echoes off the same object are most likely to occur when
you are close to a large target and are usually only a temporary
nuisance.
If the radar system is installed at a suitable height and in a
suitable location on your vessel, side lobe patterns and shadows
(blind spots) caused by obstructions such as funnels or masts will
be minimized. If you're having problems with these, you may need
to relocate the radar scanner. Consult the Installation Guide for
your radar model, or talk to your dealer or installer.
Radar: Gain mode - Manual/Range Ride/Auto
Use the radar gain mode to specify whether you want to adjust the
radar gain yourself or let the GB40 adjust it automatically.
Any changes to the radar gain mode are global and apply to all the
Radar screens. Auto is the default.
If the radar gain mode is set to Auto and then you adjust the gain
setting manually, the gain mode is changed to manual.)
