Abstract
Various methods of adaptive spatial-temporal processing of signals in a survey radar system (RS) using a digital antenna array and broadband probing signals and operating under conditions of intense active and passive interference are considered. Approaches to modeling the interference affecting RSs and algorithms for their suppression in adaptive signal processing are discussed. It is proposed to carry out modeling of signals and interference and their processing after the formation of a complex envelope of signals and conversion to the frequency domain.
