Abstract : Radar detection of aircraft on a particular scan depends in large measure on the clutter return from the target's range cell. The distribution of clutter reflectivities is often so wide that variations of many dB in signature or threshold of detection correspond to changes of only a few percent in PD (probability of detection).

An anti-clutter radar receiver
Journal of the Institution of Electrical Engineers - Part III: Radio and Communication Engineering, 1948One of the major limitations to the efficacy of radar is the presence of responses from land, sea or rain-storms in the vicinity of a target, such responses being generally known as "clutter." If the clutter is of amplitude greater than the target-echo, detection of the echo is very difficult; in many cases, however, the clutter is of amplitude smaller

Radar Detection of Small Target in Sea Clutter Using Orthogonal Projection
IEEE Geoscience and Remote Sensing Letters, 2019Sea clutter submerges the small target echo, which is disadvantageous for radar target detection. In this letter, we propose to suppress the sea clutter by orthogonal projection (OP).

High resolution radar clutter statistics
IEEE Transactions on Aerospace and Electronic Systems, 1999The generalized compound probability density function (GC-pdf) is presented for modeling high resolution radar clutter. In particular, the model is used to describe deviation of the speckle component from the Rayleigh to Weibull or other pdfs with longer tails.

Robust Clutter Rejection in Passive Radar via Generalized Subband Cancellation
IEEE Transactions on Aerospace and Electronic Systems, 2018Passive radar is known to suffer from high clutter. In this paper, a generalized subband cancellation (GSC) algorithm is proposed to achieve robust clutter rejection.

SEEK IGLOO Radar Clutter Study
1977Abstract : This report presents the procedures and results of a clutter measurement program conducted in Alaska during the summer of 1976. Both amplitude and spectral density functions were modeled from the data taken from land, sea, weather, and other forms of clutter.

Clutter emulator for radar testing
1998 IEEE AUTOTESTCON Proceedings. IEEE Systems Readiness Technology Conference. Test Technology for the 21st Century (Cat. No.98CH36179), 2002With the advent of a new airborne radar signal processing technology entitled, "Space-Time Adaptive Processing (STAP)," previous testing methods have proven inadequate. STAP algorithms minimize the amount of interference competing with the desired signal.

Radar Detection in Weibull Clutter
IEEE Transactions on Aerospace and Electronic Systems, 1976Radar detection in Weibull clutter is examined from a statistical detection viewpoint. Weibull clutter parameters are determined and related to measured values of land and sea clutter. Optimum performance in Weibull clutter is determined, and practical receivers that approach this performance are identified. Receiver performance in Rayleigh, log-normal,

Clutter suppression in search radars
1977 IEEE Conference on Decision and Control including the 16th Symposium on Adaptive Processes and A Special Symposium on Fuzzy Set Theory and Applications, 1977A comparison of MTI and Optimum Pulse-Doppler processors is presented for the case where they coherently process the same number of pulses in a radar dwell. These results are presented in terms of probability of detection versus signal-to-noise or signal-to-clutter ratio, for a fixed false alarm probability.
