Abstract
An important task of a modern radar is the study of approaches aimed at creating broadband radar systems (radars) with an adaptive phased antenna array (APAA) and the development of principles for their construction and algorithms for processing broadband signals in radars with an APAA. The main advantage of such approaches is an increase in the resolution of the system, which makes it possible to classify targets better. The article focuses on the issue of adaptive spatial filtering of active interference in a radar using digital multichannel signal processing in the frequency domain.
