Modelling and simulation of non-Rayleigh radar clutter
TL;DR: Modelling the clutter as a compound Gaussian or a spherically invariant random process allows a complete specification of the clutter suitable for use in radar design and lends itself readily to computer simulation procedures.

Theory of radar detection in coherent Weibull clutter
TL;DR: In this article, the in-phase and quadrature components of the clutter echoes have been modelled to give a Weibull probability density function (PDF) of the amplitude and a uniform PDF of the phase.

Radar detection of signals with unknown parameters in K-distributed clutter
TL;DR: In this paper, the detection of unknown parameters in correlated K-distributed noise, using the generalised Neyman-Pearson strategy is considered, where the a priori uncertainty on the signal is removed by performing a maximum likelihood estimate of the unknown parameters.

TL;DR: In this article, the in-phase and quadrature components of clutter have been modelled to give a log-normal amplitude distribution and a near uniform distribution of the phase.

TL;DR: Weibull-distributed ground clutter of cultivated land was measured using an L-band long-range air-route surveillance radar (ARSR) having a 3.0?s pulsewidth and a 1.23° beamwidth at very low grazing angles between 0.21° and 0.32° as discussed by the authors.

False-Alarm Regulation in Log-Normal and Weibull Clutter
TL;DR: In this article, a processor is described which is capable of maintaining false-alarm regulation in log-normal clutter and in Weibull clutter (and, under certain conditions, over the entire family of log normal and WeibULL distributions).

Detection of Targets in Non-Gaussian Sea Clutter
G.V. Trunk,S. F. George +1 more
TL;DR: In this article, both the log-normal and contaminated-normal distributions are proposed and yield a fairly good description of some experimental data and threshold values and detection curves are given for the mean and median detectors for both distributions.

Radar Detection in Weibull Clutter
TL;DR: In this paper, the authors examined the performance of radar detection in Weibull clutter from a statistical detection viewpoint, and determined the optimum performance of a receiver for each of the three types of clutter.

Suppression of Weibull-Distributed Clutters Using a Cell-Averaging LOG/CFAR Receiver
TL;DR: In this article, the parameters of the Weibull distribution and the threshold level for an adaptive CFAR detector are determined by calculating the mean value and the mean-squared value of the input signal voltage before it passes through a logarithmic amplifier.
