雷达穿墙检测呼吸和心跳的信号分析

Breathing and heart beating signal analysis on radar through wall detecting

雷达穿墙检测是一种新颖的生命探测技术,可用于地震后废墟中的人员搜寻以及反恐行动中人质的营救。本文对穿墙雷达回波信号进行了理论推导,引入贝塞尔函数对回波信号进行处理,仿真了呼吸和心跳的基本频率以及二者的谐波组合,仿真结果表明,结果与理论分析相一致。

Radar through wall detecting is a new technology of exploring life. It can be used in searching wounded people buried in the debris after earthquake and hostage release in the action of anti-terrorism. In this paper, radar return-wave is deduced theoretically and Bessel function is applied to it in the signal processing. The basic frequencies and harmonic combinations of breathing and heart beating are analyzed in the simulation. The simulation result is consistent with the analysis.
