Adjusting Gain on the Radar Screen Manually
For optimal radar performance, you can manually adjust the gain.
Minimizing Nearby Large-Object Interference
Nearby targets of significant size, such as jetty walls, can cause a very bright image of the target to appear on the Radar screen. This image can obscure smaller targets located near it.
Minimizing Side-Lobe Interference on the Radar Screen
Side-lobe interference may appear to streak outward from a target in a semi-circular pattern. Side-lobe effects can be avoided by reducing the gain or reducing the radar range.
