A radar device includes: a transmitter which transmits a radar signal; a receiver which receives the radar signal reflected by an object; and a signal processor which is electrically connected to the transmitter and receiver. The signal processor changes power frequency whenever scan changes during a plurality of scans, detects the object based on the transmitted signal and the received signal in each scan, and determines that the object is a track whenever the scan changes if the object repeatedly appears within a movable area during a unit scan. Therefore, the impact of power noise can be further minimized and the amount of computation required for tracking the object can be reduced. 레이더 장치는 레이더 신호를 송신하는 송신기와, 객체에 반사된 레이더 신호를 수신하는 수신기와, 송신기 및 수신기와 전기적으로 연결된 신호 처리기를 포함하고, 신호 처리기는, 복수의 스캔 동안 스캔 변경시마다 전원 주파수를 변경시키고, 각 스캔에서 송신된 신호와 수신된 신호를 근거로 객체를 검출하고, 스캔이 변경될 때마다 객체가 단위 스캔 동안 이동 가능한 영역 내에 반복적으로 나타나면 객체를 트랙으로 판단한다.
