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.

    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.
