AIRCRAFT MULTIRANGE AESA WITH RADIATION CONTROLLED BEAM AND MULTIBEAM RECEPTION OF SIGNAL Russian patent published in 2015 - IPC H01Q1/08 H01Q21/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to directed radiation and reception antenna systems. The essence of the invention consists in that AESA (active electronically scanned array) is divided into four identical modules placed on front, trailing edges of the right and left wings of the aircraft, while the active electronically scanned array modules are added by the amplitude and phase forming parts separately for the transmitted and received signals which are interconnected with the common radiator through the transceiving modules having separate transmission and reception inputs, and inputs of transmitters of the served radio equipment are connected through the power dividers, the number of outputs of which is equal to the number of radiators and inputs of the reception amplitude-phase forming part, and the same quantity of outputs of communication channels (beams), formed by the amplitude-phase forming part of reception signals, are connected to their receiver, and the output of information signal of each of receivers is connected to the input of the multiplexer added to the AESA module, the multiplex communication channel output of which is connected to the served radio equipment, which is connected through the control and monitoring unit with the AESA phase shifters operated by elements.

EFFECT: technical result is creation of AESA with the structure of construction providing at mounting in aircraft, the simultaneous circular multibeam reception of request signals and radiation of response signal towards the request a narrow beam for the purpose of stealthiness of radio emission.
