Abstract:
A method of synthesis of self-focusing multibeam adaptive array array (MB SFAAR), allowing to solve task of information support of RES in optimal management of its antenna system. Using a parametric model of the spectrum of spatial frequencies of the input signal corresponding to the models of autoregression - moving average of the synthesized structure diagrammable schema specified MB SFAAR. Performed the synthesis of the adaptive processor for adjusting the weight vector MB SFAAR. It is shown that the synthesized MB SFAAR enables the separation of signals of radiation sources according to the inclinations of their wave fronts relative to the reference element of the antenna. The results of imitation modelling are presented.
