<P>PROBLEM TO BE SOLVED: To facilitate recognition of a weak signal in azimuth-level spectrum. <P>SOLUTION: A system for processing a reception signal received by a reception sensor array constituted by plural sensors includes phasing-means, weighted-rank detection means, and band accumulation means. The weighted-rank detection means receives a phased output produced by applying phasing processing to a reception signal, from the phasing-means, and performs rank detection processing on the phased output of an azimuth direction for each frequency band using a value obtained by means of a function of an observed output signal and a compared output signal as a weighting. <P>COPYRIGHT: (C)2013,JPO&INPIT |
