Adjusting Sea Clutter on the Radar Screen
You can adjust the appearance of clutter caused by choppy sea conditions. The sea clutter setting effects the
appearance of nearby clutter and targets more than it effects the appearance of distant clutter and targets. A
higher sea clutter setting reduces the appearance of clutter caused by nearby waves, but it can also reduce or
eliminate the appearance of nearby targets.
