An unwanted pattern produced on a radarscope caused by returns from the ground. This can degrade radar in that particular area where clutter is present. The effect of ground clutter can be minimized by use of MTI, or moving target indicator, circuits in the radar equipment, resulting in a radar presentation that displays only targets that are in motion. Echoes from the sea are called sea clutter or sea return.
