Patent ID: 7132976

Claim:
An automotive radar comprising: a transmitting antenna which emits an electromagnetic wave; at least two receiving antennas which receive said electromagnetic wave reflected by a target; an antenna substrate on which said transmitting antenna and said at least two receiving antennas are arranged; a drive which, when the direction of arrangement of said at least two receiving antennas is an azimuth direction, rotates said antenna substrate in said azimuth direction to perform plural scans each from one antenna detection angle to an adjacent antenna detection angle of a plurality of antenna detection angles each formed by said at least two receiving antennas, and provides each stopping point of said antenna substrate between a scan and a next scan; and a signal processor which detects the azimuth angle of a target with respect to a reference direction during said stopping point according to received signals from said at least two receiving antennas and the rotation angle of said antenna substrate at the stopping point.
