Patent ID: 7463185

Claim:
A radar apparatus comprising: an antenna; a transmission-beam forming unit that forms a transmission beam to be transmitted from the antenna; a beam scanner that scans the transmission beam within a predetermined scanning-angle range; and a target detecting unit that detects a target based on a reception signal obtained when the transmission beam is reflected by the target and received by the antenna, wherein, when the target is located at an azimuth angle of X degrees toward at least one edge of the scanning-angle range from a predetermined azimuth angle in the scanning-angle range, the target detecting unit detects the target based on a reception-signal intensity for a transmission beam transmitted at the azimuth angle of X degrees that is lower than a reception-signal intensity for at least one transmission beam at an azimuth angle that is closer to the predetermined azimuth angle in the scanning-angle range than the azimuth angle of X degrees.
