An Experimental Classification of Radar Clutter
Proceedings of the IEEE, 1979This letter describes some experimental results concerning the classification of radar clutter-according to whether it is due to reflections from ground, weather disturbances, or migrating flocks of birds. The procedure is based on the maximum entropy method.

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,

Radar ground clutter prediction
SPIE Proceedings, 2003To investigate the potentiality of a radar ground prediction radar satellite data (SAR) have been studied for the generation of clutter estimation models. The generation of clutter statistics as well as scrutinized analysis of specific dependencies and influences of backscatter processes and behaviour is the basis for statistical clutter prediction ...

Simulation of radar clutter processing
Annual Review in Automatic Programming, 1985Abstract This paper deals with the problem of filtering a useful radar signal from the clutter. In the first part a short description of the problem is under the study, further the methods and technics applied below are stated. The unwanted signal, so called clutter, which is formed by radar echoes from ground objects, meteorological objects (cloud ...

Clutter Suppression for Wideband Radar STAP
IEEE Transactions on Geoscience and Remote Sensing, 2022Traditional space-time (ST) adaptive processing (STAP) theory is based on the assumption of narrowband or ``zero-bandwidth,'' where the decorrelation within the ST snapshot is ignored. However, with radar bandwidths increasing, this assumption becomes invalid due to the deteriorated decorrelation of the received signals within the ST snapshot.

Is there a radar clutter attractor?
Applied Physics Letters, 1990Using experimental sea clutter data obtained with an instrument-quality radar research system, we show the existence of a chaotic attractor in the clutter. This new and exciting result is in sharp contrast with the conventional stochastic modeling of clutter as some kind of a random process with certain distribution.

Computation of the entire clutter spectrum for Doppler radar has been reduced to a few simple formulas, by integration of reflected energy between constant Doppler loci, using the fourth power range law. The results are widely applicable, and have been found in agreement with both flight tests and a computer program study.

Analysis of sea clutter radar data
Proceedings of International Radar Conference, 2002We perform a detailed analysis of experimental data, collected at Osborne Gunnery Range with MacMaster University IPIX radar, to test the theoretical models developed in the literature. A comparison of the amplitude histograms with the K and lognormal distribution shows that VV data exhibit a K behaviour, while HH data are better fitted by a lognormal ...

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 ...
