Adjusting Rain Clutter on the Radar Screen
You can adjust the appearance of clutter caused by rain. Reducing the radar range also can minimize rain clutter (Adjusting the Radar Range).
The rain clutter setting affects the appearance of nearby rain clutter and targets more than it affects the appearance of distant rain clutter and targets. A higher rain clutter setting reduces the appearance of clutter caused by nearby rain, but it can also reduce or eliminate the appearance of nearby targets.
NOTE:
Depending upon the radar in use, the rain clutter settings configured for use in one radar mode may or may not be applied to other radar modes or to the radar overlay.
