Abstract
A radar device including an up-chirp tracking filter that performs a tracking process using a beat frequency at the time of an up-chirp to acquire a beat frequency, a down-chirp tracking filter that performs a tracking process using a beat frequency at the time of a down-chirp to acquire a beat frequency, target detectors that calculate distance and speed estimated values of the target for the chirps from beat frequency time series data about the chirps; an identical target determinator that determines whether or not the target detected for each of the chirps is an identical target using the distance and speed estimated values, and a distance and speed calculator that calculates a distance and a speed of the target using the beat frequency of the target which is determined to be an identical target.
