ACTIVE PHASED ARRAY Russian patent published in 2012 - IPC H01Q3/26 

FIELD: radio engineering.

SUBSTANCE: invention relates to an active phased array (APA) controlled both in direction of emission and reception and by parameters of a probing signal, operating in the composition of a pulse-Doppler board radiolocating station (BRLS). In an active phased array comprising a heterodyne, a synchroniser, the first and the second power dividers, a central processor, N transceiving modules, a vector modulator, a power amplifier, a circulator, a low-noise amplifier, an intermediate frequency filter, an analog-to-digital converter, a quadrature generator of direct digital synthesis, a quadrature balance mixer, there are serially introduced and connected second coherent heterodyne and switch of signals from the first and second microwave heterodynes, and also a preselector is introduced into each transceiving module of APA.

EFFECT: higher noise immunity to wideband noise and noise in a mirror reception channel of a board radiolocating station with an active phased array.
