成果简介	NOVELTY - Invention relates to antenna technology and in particular to methods of forming beam patterns (BP) of adaptive antenna arrays (AAA). Disclosed is a method for suppressing interference in AAA, in which an excited electromagnetic field is received by signal and interference sources, the signals received by the antenna elements of the AAA are converted into a complex form, with subsequent conversion into digital form and performing complex conjugation of values of signals converted into digital form. Complex conjugate values of signals converted into digital form are phase-shifted by multiplying their values by squares of corresponding elements of the phasing vector, which provides for setting the maximum of the AAA pattern in a given direction. Values of the suppressed digital signals are formed by adding the corresponding values of the digitally converted signals and phase-shifted complex conjugate values of the digitally converted signals. Forming a covariance matrix of suppressed signals containing covariance coefficients of values of suppressed digital signals of all antenna elements, and inverting it, complex weighting coefficients of the AAA are found by multiplying the inverse covariance matrix of the suppressed signals by the phasing vector, which provides setting the maximum of the AAA pattern in a given direction. Signals converted into digital form are multiplied by corresponding complex weight coefficients. All the obtained products are summed up to form an output signal of an adaptive antenna array corresponding to a symmetric beam pattern with a given beam orientation. USE - Antenna equipment. ADVANTAGE - Formation of a symmetrical BP and preservation of a given direction of orientation of the maximum of the BP with suppression of noise sources of the AAA in a given scanning sector. 1 cl, 5 dwg, 1 tbl
