Abstract

The analysis of estimation-correlation-compensation signal processing algorithm in presence of both broadband Gaussian interferences and a non-Gaussian interference is carried out. It is assumed that the processing realized by optimizing amplitude-phase distribution at the aperture of antenna array, 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. Analytical expression for the signal-to-interference ratio (SIR) obtained, thereby allowing optimization of the spatial structure. Based on the analytical expression of SIR, spatial structure for various signal-to-interference situations optimized.
