Abstract
There is provided a radar device. An estimating unit estimates peak signals corresponding to a target in the latest periods of each of UP and DOWN beat sections of a beat signal on the basis of histories of peak signals corresponding to the target in past periods of the UP and DOWN beat sections. A pairing unit extracts peak signals within predetermined ranges defined with reference to the estimate peak signals on the basis of the histories, and pairs the extracted peak signals. In a case where a distance to the target is equal to or shorter than a predetermined value, the pairing unit extracts peak signals corresponding to the target, from a first range which is a predetermined angular range defined with reference to the estimate peak signals, or a second range which is a predetermined transverse position range defined with reference to the estimate peak signals.
