Radar Filter Settings
Adjusting Sea Clutter on the Radar Screen
You can adjust the appearance of clutter caused by choppy sea conditions. The sea clutter setting affects the appearance of nearby clutter and targets more than it affects 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.
When using a compatible radar model, the chartplotter adjusts the sea clutter based on the sea conditions automatically.
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.
Averaging Multiple Scans on the Radar Screen
You can average the results of multiple scans on the radar screen. This can be an effective method to filter out noise and enhances the detection of consistent targets. Averaging is most effective when using a longer range.
