Abstract
An on-board radar apparatus includes a plurality of reception antennas that form a reception array antenna, the reception array antenna having two or more average pitches that do not have the relationship of integral multiplication, and an azimuth detecting unit configured to perform a phase shift so that an azimuth of the target is apparently changed by a predetermined angle, for a signal received by each reception array antenna, to perform an azimuth detection process of detecting the azimuth of the target based on the phase shift result, and to determine that the target is present in the azimuth detection range in the azimuth detection process when it is determined that the azimuths of the target detected based on the phase shift result for the signals received by the respective reception array antennas coincide with each other and to determine that the target is present outside the azimuth detection range when it is determined that the azimuths of the target do not coincide with each other.
