Echo envelope distribution in high resolution radar imaging system

摘要

The investigation results of the stochastic features of radar images speckle pattern are presented in the paper. The analytical relation between envelope distribution law of received signal and scattering parameters on the object at the radar imaging is determined at the analysis. It is shown that a probability distribution function of the radar image samples depends from the scattering technique and essentially differs in general case from Rice-Rayleigh distribution law.
