CFAR problems in a non Gaussian clutter environment
Abstract
It is noted that the most popular approach to the modeling of clutter amplitude fluctuations involves treating the clutter echoes as belonging to a priori distributions defined by known probability density functions. When the probability density function is recognized, a threshold is selected to obtain the desired probability of false alarm. An outline is presented here of a threshold estimation technique based on an evaluation of the first moments of the clutter unknown probability density function. An analysis is made of the influence of a limited number of clutter samples.
