RADAR DEVICE FOR VEHICLE AND METHOD OF CONTROLLING RADAR FOR VEHICLE

A radar device for a vehicle includes: a radar sensor disposed on either one or both of a front surface of a vehicle and a rear surface of the vehicle, and configured to emit an electromagnetic wave signal toward a road having a lane at least partially containing an electromagnetic wave absorbing paint; and a radar control unit configured to determine whether a target is an object, the road, or the lane, based on an intensity of an electromagnetic wave reflected by the object, the road, or the lane, by using a radar signal received from the radar sensor.
