METHOD OF THE MULTI-BEAM ADAPTIVE ANTENNA ARRAY BEAM PATTERN GENERATING USING THE INPUT SIGNAL SPATIAL FREQUENCIES SPECTRUM PARAMETRIC MODEL Russian patent published in 2018 - IPC H01Q3/26 

FIELD: radio equipment and communications.

SUBSTANCE: invention relates to radio engineering and can be used in radio control equipment (RCE) with multi-beam (MB) adaptive antenna arrays. Method of the multi-beam adaptive antenna array (MB AAA) beam pattern generating using the input signal spatial frequency spectrum parametric model includes radiation sources (RS) M signals recording with antenna elements (AE), generating the MB AAA input signal, input signal conversion into a complex form, its subsequent digitization, ML AAA weighting factors complex vector (WFV) formation and ML AAA input signal weighted summation by the formed complex WFV, at that, before the ML AAA complex WFV calculation, as the ML AAA input signal being received, which counts are recorded by the ML AAA AE in each k-th moment of time, performing its spatial coherent accumulation procedure followed by the accumulated signals M-fold spatial differentiation procedure, which allows to increase the interference signals suppression efficiency with a priori uncertainty relative to their sources angular position, when the of the interference signals power levels at the AA input are comparable to the desired signal power level, and the interference sources signals energy spectrum central frequency detuning from the useful signal carrier frequency is smaller than its energy spectrum width.

EFFECT: proposed is a method of the multi-beam adaptive antenna array beam pattern generating.
