Abstract
The present embodiments relate to a radar signal processing apparatus and a signal processing method thereof in which an additional beamforming is performed by reflecting an angle of a target that is positioned in front of the vehicle or by reflecting a surrounding clutter situation thereof in order to thereby improve the performance of detecting the target in front of the vehicle. According to an embodiment, a radar signal processing apparatus may include: a transmitting unit configured to transmit radar signals forward from the vehicle; a receiving unit configured to receive reflected signals among the radar signals transmitted by the transmitting unit; and a signal processing unit configured to extract a target in front of the vehicle based on the signals received by the receiving unit, wherein the receiving unit receives the radar signals by using an antenna array including a plurality of receiving antennas, the signal processing unit integrates the signals received by the plurality of receiving antennas to perform the beamforming for obtaining a desired gain, and, if there is no target in the formed beams, determines the angle of the target in front of the vehicle in order to …
