Sea clutter refers to the radar returns from a patch of ocean surface. Accurate modeling of sea clutter and robust detection of low observable targets within sea clutter are important problems in remote sensing and radar signal processing applications.

What is sea clutter?
Sea clutter refers to the signals returned from the wavy and turbulent rough sea surface. The radar returns from small targets, like submarine periscope or small boats, will be obscured by the sea clutter which makes the straightforward detection of targets, with small radar cross section, a difficult task.
What is meant by radar clutter?
Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems.
How does sea clutter work on radar?
Sea clutter refers to the radar returns from a patch of ocean surface. When a radar detects targets on or above the sea surface, it has to overcome the interference from sea echo itself.
What is the function of the sea clutter control?
The “anti- Sea Clutter” control reduces sensitivity near the center, in order to remove the clutter, but does not affect long distance detection. As you increase the “anti-Sea Clutter” control, the gain suppression moves outwards from the center of the display.
