摘要

针对在利用微多普勒雷达进行生命体征检测研究中存在的问题,设计了一种生物雷达探测系统,确定了雷达的工作模式和频率、射频收发电路及前期信号处理电路。研究了呼吸和心跳的微多普勒散射模型,并通过设计的雷达系统研究了各种人体心肺活动。从频谱的实验结果中可以区分出心跳信号和呼吸信号,因此可以利用其频谱特点起到诊断目的。设计的雷达检测系统可以用来作为一种检测人体心肺活动的工具,也可以用作在地震废墟中、雪崩等情况下探测生命体征的传感器。
        A radar detection system is proposed for the problems in the vital signs detection using micro-Doppler radar.The justification of Doppler radar working mode,frequency,RF transceiver circuit and early signals processing circuit are made for real applications of vital sign detection.The micro-Doppler scattering model of respiration and heartbeat is studied,and various human cardiac and pulmonic activities have been researched through the radar system.The pulmonic activity from the cardiac one can be distinguished from the results of the spectrum,and hence makes it possible to research spectral peculiarities for diagnostic purposes.The designed radar can be used as a tool for studying human respiratory and cardiac activity,as well as life sensor for earthquakes rubbles and avalanche.
