Abstract
A radar apparatus wherein transmission beams are set such that reception intensities corresponding to the transmission beams are gradually reduced from a center direction toward an edge direction of a scanning-angle range. For example, when a vehicle serving as a target is located in the center direction of a transmission beam, the reception-signal intensity corresponding to an adjacent transmission beam is set higher than the reception intensity in the center direction corresponding to the transmission beam. When the scanning-angle distributions of reception-signal intensities corresponding to transmission beams are detected, a scanning angle exhibiting a peak reception-signal intensity is nearer the center of the scanning-angle range than the azimuth angle at which the target is actually located. Thus, a peak reception-signal intensity corresponding to a target located in a region that is a predetermined amount outside the scanning-angle range of a transmission beam appears inside the scanning-angle range.
