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 72).

Setting

Description

FTC

This setting effects the appearance of large, hazy masses of clutter caused by rain at any

 

distance.

Rain Clutter

This setting effects the appearance of nearby rain clutter and targets more than it effects

 

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 85).
