How should you handle false echoes near land or clutter on radar?

Handling radar clutter involves tuning the system to suppress false returns while confirming real targets with other information. When echoes from land or clutter appear, adjust the receiver gain and enable clutter suppression so that stationary or repetitive clutter is reduced without discarding true moving targets. Verifying with charts, radar overlays, AIS data, and known landmarks helps you identify whether an echo corresponds to a charted feature or a real object. Then look for motion across sweeps: real targets will move relative to your vessel, while land and most clutter remain fixed. Relying on range or distance changes alone isn’t reliable, since simply increasing range can hide clutter or shift what you see; the robust approach is tuning, cross-checking with aids, and confirming motion.
