The analysis of nonlinear spatial compensation for a complex of interferences using an optimal spatial structure

Abstract

The analysis of estimation-correlation-compensation signal processing algorithm in presence of both broadband Gaussian interferences and non-Gaussian interference is carried out. It is assumed that the processing realized by optimizing amplitude-phase distribution at the antenna array aperture, by optimizing the spatial structure of processing system, as well as by the subsequent non-linear compensation of non-Gaussian interference and by correlation processing. The analytical expression for the signal-to-noise ratio is obtained, thereby allowing making the spatial structure optimization.
