摘要
雷达穿墙检测是一种新颖的生命探测技术,可应用于地震后废墟中人员搜寻以及反恐行动中人质的营救等场合。对雷达信号穿墙后的衰减和波长选择进行了归纳总结,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情况,结果与理论分析相吻合。
Radar echo signal through wall detecting is a kind of new exploring life technology used for seeking wounded personnel on the ruin of earthquake and rescuing hostages from terrorists. The attenuation of radar wave after penetrating wall and the wavelength selecting were summarized, radar echo signal was theoretically deduced, Bessel function was introduced into processing echo signal and the basic frequencies and harmonic combinations of breathing and heart beating were simulated. The simulation result is consistent with the theoretical analysis.
