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 ( page 63 ).
Setting Description
FTC This setting affects the appearance of large, hazy masses of clutter caused by rain at any
distance�
Rain Clutter This 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 and FTC settings configured for use in one radar
mode may or may not be applied to other radar modes or to the Radar Overlay ( page 75 ).
