FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio engineering and can be used in design of radioelectronic facilities and systems for various special purposes, for example, systems for space communication with mobile objects. Method for synthesis of a multi-beam self-focusing adaptive antenna arrays (MB SFAAA) by using a parametric correlation matrix (CM) model of a received signal comprises setting the initial data according to the number of antenna elements (AE) N, their characteristics, position in space, number and characteristics of analog-to-digital converters (ADCs), type and technical implementation of beam-forming arrangement (BFA) block and digital adaptive processor (AP) unit formed by digital signal processor (SP) and digital control device (CD) unit calculating a value of weighting factor vector (WFV) of the MB SFAAA, which provides the maximum directivity factor (DF) of the antenna, and the synthesis of the digital SP unit is performed as a synthesis of a digital device that separately calculates the values of the amplitude-phase distribution of the signals of radiation sources (RSs) at the MB SFAAA equipment, with an arbitrary form of their phase front. Synthesized MB SFAAA comprises AE units, connected in parallel through the ADC units with the digital BFA unit and the digital AP unit including a digital SP unit that calculates the APHD of the RS signals, whose values are transmitted to the digital CD unit calculating the MB SFAAA, value of which is transmitted to the digital BFA unit for performing weighted summation of the signals received by the AE units, the output of the digital BFA unit is output of the MB SFAAA.
EFFECT: technical result is increased efficiency of the MB SFAAA signal reception.
