摘要:: 本研究采用微波雷达法研制出基于微波非接触人体呼吸检测系统对人体呼吸进行检测，并设计了两种测试方案。第一种方案与权威商用呼吸设备做同步数据采集比较；第二种方案在不同人群及人体不同体位情况下进行呼吸检测，体位分为平躺、侧躺、坐立。通过系统测试，验证了该微波系统检测信号的唯一性，即检测出的信号就是真实呼吸信号；同时验证了微波系统具有较高的鲁棒性。说明基于微波非接触呼吸检测系统可对人体呼吸进行有效检测，进一步为临床医学提供一种非接触检测设备。

Abstract:: We adopted the microwave radar method and developed a microwave non-contact human respiratory detection system to detect human respiration.We designed two test schemes. The first scheme was compared with authoritative commercial respiratory equipment for synchronous data collection. The second scheme was used for respiratory detection in different populations and different body positions. The position was divided into lying, lying on the side and sitting upright. The uniqueness of the detection signal of the microwave system was obtained through system testing—the detected signal was the real breathing signal, and the microwave system was proved to have high robustness. It shows that the microwave non-contact respiratory detection system can effectively detect human respiratory, and further provides a non-contact detection device for clinical medicine.
