レーダ装置
Document Type and Number:
Japanese Patent JP5766303
Kind Code:
B2
Abstract:
Disclosed is a radar device including a transmitter 1 that transmits, as a radar wave, a transmission signal, a signal processor 2 that receives a reflected wave from a target and generates a received signal and that specifies a beat frequency for each chirp on the basis of the received signal and the transmission signal, an up-chirp tracking filter 19 that performs a tracking process on the basis of the beat frequency at the time of an up-chirp to acquire a beat frequency of the target, a down-chirp tracking filter 20 that performs a tracking process on the basis of the beat frequency at the time of a down-chirp to acquire a beat frequency of the target, target detectors 6 and 7 that calculate distance and speed estimated values of the target for the chirps on the basis of beat frequency time series data acquired for the chirps respectively; an identical target determinator 8 that determines whether or not the target detected for each of the chirps is an identical target on the basis of the distance and speed estimated values of the target calculated for each of the chirps, and a distance and speed calculator 11 that calculates a distance and a speed of the target on the basis of the beat frequency, for each of the chirps, of the target which is determined to be an identical target.
