ADAPTIVE ANTENNA SYSTEM FOR PANORAMIC RADIO RECEIVER Russian patent published in 2019 - IPC H01Q3/26 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering, in particular to the field of antenna technology, and can be used as part of panoramic radio receivers when monitoring the radio-electronic environment and estimating the parameters of signals from radio emission sources. Antenna system contains n antenna elements, n preselectors, m beamforming units. Outputs of each of the preselectors are connected to the corresponding inputs of the beamforming unit. Output of each antenna element is connected to the first input of the corresponding preselector, and the second inputs of all the preselectors are combined and are the input to control the restructuring of the preselectors. In this case, (n+1)^th inputs of the beamforming units are the switching inputs of the adaptive antenna system, (n+2)^th inputs are the inputs of the initial installation of the adaptive antenna system, (n+3)^th inputs are code inputs frequencies, and the first outputs of the beamforming units are the outputs of the adaptive antenna system. Inputs of the controller are connected to the second outputs of the respective beamforming units. Each of the controller outputs is connected to the (m+4)^th input of the corresponding beamforming unit, (n+5)^th inputs of the beamforming unit are connected to the second inputs of the preselectors.

EFFECT: technical result is to increase the capacity of the panoramic radio receiver, to increase the gain of the AAS and to increase the signal-to-noise ratio + noise at the output of each beamforming unit when estimating signal parameters.
