Statistical characteristics of the received signal for stochastic surface models

This paper describes the stochastic model of the scattered electromagnetic field. Unlike common-used functional-determined models the proposed is characterised by amplitude/phase fluctuation of the received signal.This paper derives the statistical characteristic of the input signal and describes algorithm for its estimation in post-processing and real-time processing modes. Achieved characteristics allow the mapping and estimation of the surface models more accurate, moreover, such processing increase space resolution of synthetic aperture radar.
