Radar detection in K-distributed clutter
IEE Proceedings - Radar, Sonar and Navigation, 1994The paper compares two newly proposed detection schemes for targets in K-distributed clutter: the first implements generalised likelihood ratio test, and the second represents a discrete realisation of the classical Neymann-Pearson detector. Results indicate that the two optimisation strategies yield substantially equivalent performance, but the ...

Clutter is defined as any unwanted radar return. The presence of clutter in a range/Doppler cell complicates the detection of a target return signal in that cell. In order to quantify the effect of clutter on the probability of detection, we must first specify sets of models suitable for representing the clutter and target. The simplest and most common

Radar detection in coherent Weibull clutter
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1987In this correspondence, a new model for the Weibull clutter is presented. Then attention is turned to the design of the optimum radar processor to detect an a priori known target signal embedded in coherent Weibull clutter. An original detection scheme is presented and the corresponding performance is assessed.

Metal shields (or fences) are useful in reducing the ground clutter received by a radar. The design of a clutter shield for an L-band monopulse radar employing a 60-ft parabolic reflector with Cassegrainian geometry is verified by scale-model measurements at K a -band.

Adaptive radar clutter suppression
MTS/IEEE Oceans 2001. An Ocean Odyssey. Conference Proceedings (IEEE Cat. No.01CH37295), 2002The clutter return presents a severe problem in target detection for radar systems. Conventional radar systems assume the clutter is stationary, with energy concentrated in the low frequency domain. To minimize the effect of clutter, radar systems use a fixed high pass filter (HPF) to eliminate the clutter.

Optimum radar signal processing in clutter
IEEE Transactions on Information Theory, 1968This paper considers the joint optimization of a class of radar signals and filters in a number of clutter-pins-noise environments. The radar signal processor in this case will be optimum in the sense that its output at the time of target detection yields the maximum ratio of peak signal power to total interference power.

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

The use of constant-false-alarm-rate (CFAR) techniques to keep false alarm rates at a suitable low level is reviewed. Radar resource management for clutter suppression, a novel approach for multifunction phased-array radar that can more effectively suppress clutter, is proposed.

MIMO radar limitations in clutter
2009 IEEE Radar Conference, 2009Recently discovered bounds for the clear-area available in the ambiguity domain for a MIMO radar waveform set are shown to be a significant limitation in radar applications having extended scatterer distributions. These limitations are demonstrated using an example from an experimental MIMO over-the-horizon radar.
