摘　　要：随着信号处理技术和雷达技术的不断发展,信号测量不仅可以获取目标的距离、方位、速度等信息,还可以提取目标的振动和旋转等变化细节信息。在灾后人员搜救过程中,特别是倒塌建筑人员搜救过程中,如何通过无线电技术手段进行指导,是应急保障和无线电管理部门急需解决的问题。利用微多普勒频移技术,探测生命体征具有十分重要的现实意义。With the continuous development of signal processing technology and radar technology,signal measurement can not only obtain information such as distance,orientation and speed of the target,but also extract information about changes in detail such as vibration and rotation of the target.In the post-disaster personnel search and rescue process,especially in the collapsed construction personnel search and rescue process,how to guide through radio technical means is an urgent problem for emergency security and radio management.The detection of vital signs using micro doppler frequency shifting techniques is of great practical importance.
