摘　　要：本文根据多普勒频移对生命信号进行探测和分析,利用虚拟仪器技术和LabVIEW信号处理工具包,构建生命探测仪硬件系统和软件系统,完成人体特征信号提取和分析。该方法比传统方法信号失真度小,能可视化的观测与分析信号频谱。生命信号的探测技术可用于地质灾害中人员营救,以及特殊条件下人员位置的判定。Using the virtual instrument technology and signal processing toolkit of Lab IEW, a life detector hardware and software systems have been build to complete the human characteristics of signal extraction and analysis, based on Doppler frequency shift to detect and analyze the signals of life. Compared with the traditional way, this method has a small-signal distortion and the signal spectrum can be observed and analyzed visually. Life signal detection technology can be used for rescue personnel in the geological disasters, as well as to determine the location of personnel under special conditions.
