Radio monitoring of radio emission sources (RES) requires their localization. The problem of localization of RES in the presence of inaccurate a priori information about the direction of the arrival of electromagnetic waves is relevant, despite the large number of works devoted to this topic.

The aim of the article is to increase the efficiency of the radio monitoring complex.

The paper considers options for using adaptive spatial filtering of signals to obtain information about the direction of signal arrival. A variant of practical application of direct estimation of amplitudes and phases of received signals to determine signals and interference has been proposed.
