Abstract
A stationary object detection method for a scanning radar wherein, of peaks generated based on a radar signal reflected from a target, peaks having substantially the same frequency are grouped together, and a decision is made as to whether or not the frequency of the grouped peaks is equal to/higher than a predetermined value, and wherein if the peak frequency is equal to or higher than the predetermined value, then a decision is made as to whether or not the number of grouped peaks is equal to or greater than a predetermined number and, if the number of peaks is equal to or greater than the predetermined number, it is decided that the target is an overhead bridge candidate or an overhead bridge. Further, pairing is applied to peaks signals obtained from the target determined as the overhead bridge candidate, to detect a relative velocity with respect to the target, and if the relative velocity is substantially equal to the speed of a vehicle equipped with the radar, it is decided that the target is an overhead bridge.
