Abstract

The article describes the algorithm for controlling the shape of the directional pattern and orienting of its main beam to the source of the navigation signal, the spatial position of which is unknown in advance. The article presents the block diagram of the adaptive antenna system that realizes this algorithm on the basis of the direct inversion of the covariance matrix of the input actions. A variant of forming a multi beam directional pattern with independently controlled maxima is proposed due to the use of parallel processors. The results of modeling are presented.
