Abstract. Aerial vehicles and methods of radio electronic warfare quickly improve, therefore, development of radar system based on the digital antenna array is a very important problem nowadays. Currently such radar system is being developed by engineers’ group of MDCS Institute of National Research University of Electronic Technology. Several technical solutions were implemented during the development, such as the use of a circle concentric antenna array. General structure of developed radar system is described in detail in this work. Also its specific blocks, such as an active phased antenna array modulator, reference signal forming unit and local oscillator signal distribution unit are discussed briefly. Use of classic antenna array is coupled with certain problems in the cases of wide sector of radiation and thin scanning ray forming. In this radar system the solution of the most crucial problems is the circle concentric placement of transmitters on the receiving digital antenna array. Optimal structure for this radar system is a hybrid one that provides required characteristics for detecting subtle targets. In this case transmitting part is represented by active phased antenna array that forms relatively wide highlighting beam whereas receiving part is represented by digital antenna array that provides several thin scanning beams.

Key words: digital antenna array, DAA, multichannel radar, APAA, UAV.
