Abstract
The disclosure relates to a radar device for a vehicle, enabling to determine a target satisfying a pairing condition for finding an intersection point by using a combination of a pair of up-chirp and down-chirp signals with an added down-chirp signal, without an additional hardware resource. The radar device includes at least: a transmission unit configured to transmit, through the transmission antenna, a transmission signal including a pair of up-chirp and down-chirp signals having predetermined slopes, and an added chirp signal having a slope different from the slopes; 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; and a signal processing unit configured to determine the target satisfying the pairing condition for finding an intersection point through a combination of at least one of a pair of the up-chirp and down-chirp signals.
