连续波生物雷达的实验和仿真

概述了基于生物电效应的人体生命特征探测假说。为了作进一步的探讨,设计和制作了一个X频段连续波雷达实验系统,通过实验测试和MATLAB数字信号处理,得到人体呼吸和心跳等生命特征信号。根据该假说和实验参数建立了连续波雷达系统的仿真模型,并在ADS平台上进行了仿真。仿真和实验结果表明,两者的信号特征基本一致。

Experiment and Simulation for Continuous Wave Biological Radar

A hypothesis based on bioelectric effect concerning human body life sign detection is reviewed.To further explore the hypothesis,an X-band continuous wave radar test system is designed and implemented.Breathing and heart beating signals are obtained by the measurement and digital signal processing tool of MATLAB.According to the hypothesis and test data,a simulation model is established and then simulated using ADS platform.The result shows that a basically satisfactory agreement between the test and simulation is obtained.
