Abstract
The present disclosure relates to a radar apparatus for vehicle and a method of removing a ghost of the radar apparatus for vehicle by determining a grating lobe ghost based on a reception signal received through linearly and equally spaced receiving antennas and unequally spaced receiving antennas. The radar apparatus comprises: a transmitting unit configured to transmit a predetermined transmission signal to the front of the vehicle through the plurality of transmitting antennas; a receiving unit configured to receive a reception signal generated from the transmission signal transmitted by the transmitting unit and reflected and returned by the target positioned in front of the vehicle through the plurality of receiving antennas and the additionally included receiving antenna; and a signal processing unit configured to remove a grating lobe ghost by using the difference of a gain obtained through a digital beamforming result and the reception signal.
