摘要

在本文中,我们研究使用调频连续波(FMCW)雷达来检测人的生命体征,即呼吸和心跳。在考虑到带宽可用性和与其他系统的干扰等设计因素的情况下,选择了一个最佳频率来观察生命符号。一种新型的紧凑型x波段FMCW雷达已经在TNO实验室建成,并在这里给出了实验结果,证明了这种新系统探测生命迹象的能力。

FMCW radar for life-sign detection
In this paper we investigate the use of Frequency Modulated Continuous Wave (FMCW) radars for detecting life-sign of people, i.e. breathing and heartbeat. An optimum frequency has been selected to observe life-sign, taking into consideration also design factors, such as bandwidth availability and interference with other systems. A new compact X-band FMCW radar has been built at TNO laboratories and experimental results are presented here, which demonstrate the ability of this new system to detect life-sign.
