Abstract. A method for suppressing pulse interference in adaptive antenna arrays is proposed, characterized by the use of a procedure for logical signal processing in the main and compensation channels to form a covariance interference matrix. To form the directional pattern of the main channel, weight coefficients are used to ensure a low level of side lobes. The radiation pattern of the compensation channel is obtained by subtracting the radiation patterns of orthogonal linear antenna arrays highlighted in the opening of the antenna array. Logical processing is used to determine the time domain, which does not contain a signal component, but contains external interference. It is shown that the use of logical processing of the main and compensation channels ensures the exclusion of the signal component from the covariance interference matrix and increases the noise immunity of the antenna.

Key words: pulse interference, directional patterns, logical signal processing, spatiotemporal signal processing.
