Abstract:

As for today digital active phased array antennas (DAPAA), based on the principle of functioning using digital diagram formation, are actively used as part of spacecraft and unmanned aerial vehicles in solving radio communication and radar problems. At the same time, for the purposes of radar, DAPAA allows you to perceive all the information contained in the structure of spatiotemporal electromagnetic fields in the opening of the array and transform it into data on the presence and parameters of objects, providing deep compensation for broadband interference signals, which, combined with the expansion of the dynamic range when accumulated during spatiotemporal processing, provides high noise immunity of radar stations. To solve communication problems, DAPAA allows you to form several beams simultaneously, which allows you to simultaneously serve several areas at once with the possibility of dynamically changing the bandwidth in the channels due to variations in partial power.
