Abstract
A method that can locate the center of a target even when the target is a large vehicle, and that, when a plurality of beams are reflected, determines whether the reflected beams are from the same target or not, wherein, of peaks generated based on a radar signal reflected from the target, peaks whose frequencies are substantially the same and whose reception levels are not smaller than a predetermined value are selected and, when a plurality of such peaks are selected, a center angle between the angles of the leftmost and rightmost peaks is obtained, and the thus obtained center angle is taken as an angle representing the target. Further, the plurality of peaks are paired up to detect a distance, relative velocity, and displacement length for each of reflecting points on the target, and when the differences in these values are all within respectively predetermined values, the plurality of peaks are determined as being peaks representing the same target.
