Abstract
The disclosure relates to a radar device for a vehicle, enabling distance and velocity of a target approaching at a high speed in a short distance to be measured while securing a detection performance of the target. The radar device includes at least: a transmission unit configured to transmit, as a transmission signal, a multi-chirp signal having different slopes through the transmission antenna; a reception unit configured to receive, through the reception antenna, a reception signal that is the transmission signal reflected on the target located before the vehicle, in which the transmission signal is transmitted by the transmission unit; and a signal processing unit configured to calculate a frequency difference between the transmission signal and the reception signal, frequency variation according to a distance of the target, and frequency variation according to the velocity of the target to measure the distance and velocity of the corresponding target.
