Step reduction of the displacement of the difference pattern of a monopulse phased-array antenna
Abstract
The paper examines the possibility of improving the direction-finding precision for a monopulse phased array by means of the preliminary synthesis and recording of discrete phase distributions (PDs). The proposed method uses discrete analogs of gradient algorithms, based on coordinate-descent strategies. It is shown that the proposed method for obtaining optimal PDs is an effective means for improving the direction-finding precision of monopulse phased arrays.
