Abstract

This paper presents a novel apnea detection and respiration rate estimation method using impulse-radio ultra-wideband (IR-UWB) radar. The proposed method utilizes amplitude, time of arrival, and power in the selected band. The experimental results show that respiration rate can be estimated accurately using proposed method. And, it is shown that the selectivity between apnea and respiration can be improved more than 50 dB using the proposed method.

본 논문에서는 IR-UWB 레이다 신호를 이용하여 무호흡 검출과 호흡수를 측정할 수 있는 방법을 제안한다. 제안한 방법에서는 무호흡 검출과 호흡수 측정을 동시에 지원하기 위해서 레이다 신호의 크기, 도래시간 및 선택된 주파수 대역에서의 전력 정보를 이용한다. 하드웨어 실험을 통해서 제안한 방법을 사용하여 정확한 호흡수 측정이 가능함을 보인다. 또한, 제안한 방법을 사용하여 무호흡과 호흡의 선택비가 최소 50 dB 이상이 됨을 보인다.
