FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio engineering and can be used in radio technical control equipment (RTC) with multi-beam adaptive antenna arrays. Method for synthesizing a multi-beam self-focusing adaptive antenna array (MB SFAAA) using a parametric model of the spatial frequency spectrum (SFS) of emission sources (ES) signals comprises the setting of the initial data on the number of antenna elements (AE), their characteristics, spatial location and type of the beam-forming network (BFN), with the subsequent construction of the adaptive processor (AP) of the MB SFAAA, which calculates the vector of the weight coefficients of the MB SFAAA, at which the signal-to-interference + noise ratio at the antenna output is maximized. Construction of the MB SFAAA AP is performed using the parametric model of the SFS of a signal received by the MB SFAAA based on the minimum mean square error criterion. Synthesized MB SFAAA consists of the AE units connected in parallel to the BFN unit and the AP unit, including a spatial signal processing unit (SSP), a signal processor unit connected to the SSP unit via a feedback loop and a control unit.
EFFECT: technical result is to increase the efficiency of suppression of signals from sources of interference.
