Abstract
Various methods of adaptive space-time signal processing in a survey radar system with a digital antenna array and wideband sounding signals intensively influenced by active and passive interferences are considered. Approaches to simulation of interferences acting on radars and their suppression by adaptive signal processing are discussed. It is proposed to simulate signals and interferences and their processing after transformation to the complex envelope in the frequency domain.
