What is clutter echo?

Clutter echoes are those received from undesired scatterers such as land, sea, rain, snow, chaff, clouds, birds, insects, aurora, and meteors. Good radar practice requires that these clutter echoes be eliminated or minimized so as to prevent degraded detection of desired target echoes.

What is clutter signal?

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 affect the detection of targets on the radar screen display?

Target Detection

(b) Clutter saturates receiver or display. 1. Targets weaker than the ambient clutter. A target which returns a signal that is weaker than the clutter surrounding it cannot be detected, because any technique used to suppress the clutter will also suppress the echo of the wanted target.

How clutter affects the radar observation?

Clutter echoes can seriously limit the capability of a radar system; thus, a significant part of radar design is devoted to minimizing the effects of clutter without reducing the echoes from desired targets.
