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 ...

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.

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.

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 ...

An Improved CA-CFAR Method for Ship Target Detection in Strong Clutter Using UHF Radar
IEEE Signal Processing Letters, 2020In this letter, the application of ultra-high frequency (UHF) radar for ship target detection over river is investigated for the first time. Due to the wide beam width of antenna, the ship detection of the UHF radar suffers from the broaden river ...

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.

This paper studies the design of efficient detector for radar targets in compound-Gaussian clutter with inverse Gaussian texture (CG-IG clutter). Due to inclusion of the modified Bessel function, the optimum coherent detector in CG-IG clutter cannot be ...

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 ...

High resolution radar clutter classification
Proceedings International Radar Conference, 2002Classification of high resolution radar echoes is carried out using the generalized compound probability density function (GC-pdf). The system noise, usually referred to as thermal noise, is incorporated in the model. The classification procedure comprises the estimation of the parameters of the GC-pdf.
