Radar device for vehicle and control method thereof

A radar device for a vehicle, comprising:

• an antenna part comprising a plurality of transmitting antennas and a plurality of receiving antennas, the antenna part being formed of array antennas;
• a signal processor for detecting a target by processing a radar signal and a reflected signal transmitted and received through the antenna part;
• and
• a feeding part for correcting phases of the radar signal and the reflected signal through a feeding line connecting the antenna part and the signal processor,
• wherein the signal processor corrects a phase of a noise signal based on phase information of a feeding line such that a false target corresponding to the noise signal incoming is detected at a specific angle outside a detection area of the radar device, and
• wherein the phase information includes a phase correction value set to re-correct the phase of the reflected signal to detect the target, and the phase correction value varies depending on at least one of shape and length of the feeding line, a distance between the receiving antennas, and the material of a PCB substrate on which the receiving antennas are disposed.
