摘要
介绍了呼吸、心率的雷达式非接触检测系统的硬、软件设计思想和方法。研究了其非接触检测技术。在探测信号功率P <1mW ,探测距离S <10m ,检测对象着各类衣服的情况下 ,较高质量的检测出人体呼吸和心动信号。结果表明 :该技术方法和系统检测灵敏度高 ,对人体无害 ,是一种可行的、很有前景的呼吸。
The paper introduces the design of hardware and software of non contact detection system for breathing and heartbeat in human body with radar principles and technology. The detection technology is discussed. Under conditions of the illuminating power P<1mW and the distance S<10m, the non contact breathing and heartbeat measarement, can be made in different positions and with different clothing on the subject. The results show that the system with the technology has a high sensitivity, and is harmless to the health. It is a practicable non contact detection technology for breathing and heartbeat of human body.
