摘要:

在生命特征信号处理的研究中,由于人体状态、姿势及位置等的不同,使得其研究结果产生了很大差异。因此,本文设计了一种基于生物雷达监测系统的用于生命特征信号研究的模拟系统。该系统为生命特征信号的处理研究提供了定量稳定的目标信号,并且其信号频率、幅度等参数连续可调。本系统通过模拟人体的心肺运动,实现了非接触式生命探测实验。通过不同条件下对模拟系统的实验测试,实验结果证明了在不同工况下,该系统具有更好的信噪比,且系统是全局稳定的,提高了系统的实用性。

In the research of life characteristic signal processing, because of different status, postures and positions, the results produce huge difference. Therefore, this paper designs a monitoring system which is based on biological radar simulation system, and it could be used in the study of life cha-racteristic signal. The system provides target signals with stable quantitation for the research of life characteristic signal processing, and the signal parameters such as frequency, amplitude are adjustable. The system realizes the non-contact life detecting experiment through simulating the cardio of human. Through the test of the simulation system under different conditions, the expe-rimental results prove that under different conditions, the system has better SNR and is globally stable, improving the practicability.
