PURPOSE: Radar and a signal processing method thereof are provided to shorten a signal processing time by reducing the time to process a reaction signal which is received in each chirp signal. CONSTITUTION: A transmission unit(11) transmits a transmission signal. A receiving unit(12) receives a reaction signal in which the transmission signal is reflected to a target and returned. A signal processing unit(13) obtains the information of a vehicle and a distance between a target and the vehicle based on the transmission signal of one cycle and a reaction signal. The signal processing unit determines whether the transmission signal of a next cycle is transmitted to one chirp signal of an up chirp signal or a down chirp signal. |
