| 摘 要： | 通过理论分析和计算机仿真,指出用多普勒雷达理论研究生命特征探测时,在由基带信号获取心跳和呼吸信号的方法,以及呼吸和心跳信号的幅度差别两方面,理论与实验存在不一致性。提出了一种基于生物电效应的连续波雷达探测生命特征的观点,并通过电磁散射理论分析表明,可以将系统表示为以调幅-调相波为特征的简单数学模型。

| Abstract: | Through theoretical analysis and computer simulations,it is found that there are two inconsistencies when using Doppler radar theory to study the mechanism of vital sign detection.One is the method to get heartbeat and respiration signal from baseband,and the other is the amplitude difference between the two signals.A new viewpoint is also presented for this topic based on bioelectrical effect,and a simple mathematic model is established which is characterized by an AM-PM wave system in virtue of electromagnetic scattering analysis. |
