<p><P>PROBLEM TO BE SOLVED: To achieve a wide range of monopulse processings, even if there are constraints with respect to mounting. <P>SOLUTION: A radar apparatus comprises a receiving antenna 12, consisting of a plurality of antenna elements for receiving radio waves as received signals that are emitted into space and then reflected by a target object, and a signal processor 20 that detects the distance to the target object, the speed of the target object, and azimuth thereof, based on digital signals converted from analog signals that the received signals output from the receiving antenna 12 is down-converted to a predetermined frequency band. The signal processor 20 performs monopulse processings, based on the outputs of a first processing unit for processing the outputs of parts of a plurality of the antenna elements of the receiving antenna 12 as a batch unit and a second processing unit, different from the first processing unit for processing the outputs of parts of a plurality of antenna elements of the receiving antenna 12, as another batch unit. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
