Zusammenfassung:	The present invention discloses an occupant detection device based on an IR-UWB radar sensor, which comprises: an IR-UWB radar sensor which is installed in at least one indoor location and periodically transmits IR-UWB impulse signals to a predetermined surveillance area to detect vital signs of occupants including breathing and a heart rate; a motor unit which is connected to the IR-UWB radar sensor and rotates the IR-UWB radar sensor left and right with respect to the ground within a predetermined angular range; a signal processing unit which, whenever a reflected signal corresponding to each of the IR-UWB impulse signals is received, converts the reflected signal into a frequency domain signal for the same designated time period; a frequency analysis unit which analyzes the frequency domain signal and classifies the same into a breathing section and a heart-rate section; a peak extraction unit which extracts a peak signal above a predetermined level for the breathing section; and an occupant counting unit which counts the peak signal extracted by the peak extraction unit to derive the number of occupants. According to the present invention, the detection ability can be equally exerted even when there are partitions, walls, and obstacles. 본 발명은 실내의 적어도 하나 이상의 개소에 설치되고, 미리 정해진 감시영역으로 IR-UWB 임펄스 신호들을 주기적으로 송신하여 재실자의 호흡 및 심박을 포함하는 생체 신호를 탐지하는 IR-UWB 레이더 센서; 상기 IR-UWB 레이더 센서에 연결되어 미리 정해진 각도 범위 내에서 상기 IR-UWB 레이더 센서를 지면에 대해 좌우로 왕복회전시키는 모터부; 각각의 IR-UWB 임펄스 신호에 대응하는 반사 신호가 수신될 때마다 지정된 동일 시간 구간에 대해 주파수 도메인 신호로 변환하는 신호 처리부; 상기 주파수 도메인 신호를 분석하여 호흡 구간과 심박 구간을 구분하는 주파수 분석부; 상기 호흡 구간에 대하여 정해진 레벨 이상의 피크 신호를 추출하는 피크 추출부; 및 상기 피크 추출부에 의해 추출된 피크 신호를 카운트하여 재실자의 수를 도출하는 재실자 카운트부;를 포함하는 IR-UWB 레이더 센서 기반 재실자 감지장치를 개시한다.
