<p><P>PROBLEM TO BE SOLVED: To improve processing speed by alleviating a processing load in radar signal processing. <P>SOLUTION: An apparatus for processing a radar signal is equipped with: an input round robin control circuit 71 that distributes and processes received signals of reflected waves per azimuth; a plurality of weight calculation units 72 that calculate a weight for forming synthetic beam to suppress unnecessary waves based on received signals per azimuth; and a beam synthetic device 76 that weighs the received signal per azimuth by a weight to form a synthetic beam. The weight calculation unit 72 divides the received signals per azimuth into a plurality of range data in a distance direction. A first range weight calculation circuit 73 calculates a first weight from a first half of range data. A second range weight calculation circuit 74 calculates a second weight from a second half of the range data. A beam synthesizing circuit 76 weighs the second half of the range data by the first weight, and the first half of the range data by the second weight. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
