Analytical form of distribution functions of received signals for high resolution coherent radar

The results of investigation of stochastic features of an echo signal received by a high-resolution coherent radar are shown in the paper. The analytical relation between discrete model parameters of scattering and distribution laws of received signal magnitude was established in this analysis. It was shown that the probability density function of signal magnitude depends on the scattering technique, in the general case essentially differs from the Rice-Rayleigh distribution. and cannot be written in explicit form. The proposed approach allows us to obtain analytically distribution functions which describe the stochastic features of scattered signal magnitude with good accuracy.
