레이더를 활용하여 차량의 후석 승객의 정확한 위치를 2차원으로 분석하여 후석 승객 존재 여부를 감지하기 위한 감지 장치 및 방법이 개시된다. 일 실시예에 따른 차량 후석 승객을 감지하는 감지 장치는, 복수의 안테나를 통해 빔 포밍 방식으로 레이더 신호를 송신하는 레이더 송신부; 복수의 안테나를 통해 반사 레이더 신호를 수신하는 레이더 수신부; 및 상기 반사 레이더 신호를 이용하여 2차원 탐색 면적을 생성하고 승객의 호흡에 따른 피부 움직임에 대응하는 주파수 성분을 확인하여 후석의 승객 유무를 판단하는 제어부를 포함한다.

    Disclosed are a sensing device and a sensing method for sensing whether a passenger exists on a rear seat by analyzing an accurate position of the passenger on the rear seat of a vehicle in two dimensions. According to one embodiment, the sensing device for sensing the passenger on the rear seat of the vehicle comprises: a radar transmission unit transmitting a radar signal by a beam forming method through a plurality of antennas; a radar reception unit receiving a reflection radar signal through the plurality of antennas; and a control unit generating a two-dimensional search area by using the reflection radar signal and checking a frequency component corresponding to movement of skin caused by breathing of the passenger to determine whether the passenger exists on the rear seat.
