Abstract

Provided is a radar device capable of preventing mispairing from occurring, and obtaining a distance to a target and a relative velocity to the target even if at least one of the peak frequencies of beat signals cannot be extracted and pairs of the peak frequencies cannot be generated. A target estimation part () estimates a distance (RN) to a target () and a relative velocity (VN) to the target () based on a distance (RO) to the target () and a relative velocity (VO) to the target (), which have been decided by a target decision part () in a previous cycle, when at least one of the peak frequencies of the beat signal cannot be extracted and the pair of the peak frequencies cannot be generated.
