Disclosed herein is a driver assistance system and a control method thereof. The driver assistance system includes a radar installed in a vehicle to detect other vehicle driving outside of the vehicle, and configured to acquire radar data comprising position information of the other vehicle, and a controller configured to calculate a risk of collision based on a relative distance of the other vehicle with respect to the vehicle. The controller generates a first region of interest partitioned along an expected driving path of the vehicle, generates a second region of interest during the vehicle moves along the expected driving path of the vehicle, when other vehicle is detected in the first region of interest, and calculates a relative distance of the other vehicle detected in the second region of interest.
