Research on a New Comprehensive CFAR (Comp-CFAR) Processing Method

IEEE Access, 2019
Since the clutter statistics of marine radar are non-stationary and difficult to ascertain, the constant false-alarm rate (CFAR) processor based on some clutter statistical characteristics is hard to obtain the CFAR performance.

Intelligent Suppression Method for Ionospheric Clutter Based on Clustering and Greedy Strategy

Leida xuebao, 2020
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 ...

Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]

, 2011
Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.

Doppler characteristics of sea clutter. [PDF]

, 2010
Doppler radars can distinguish targets from clutter if the target's velocity along the radar line of sight is beyond that of the clutter. Some targets of interest may have a Doppler shift similar to that of clutter. The nature of sea clutter is different
