摘　　要：针对传统的无线电波透视法获取信息量少及探测工作繁琐等问题,提出了一种基于冲激脉冲的时域脉冲式无线电波透视法;仿真分析了理想脉冲电磁波透过一定厚度的不同介质后在有限频带内的频率响应。仿真结果表明,基于冲激脉冲的时域脉冲式无线电波透视法具有更宽的频率范围,可增加提取的信息量,提高探测精度;不同介质的电性参数和吸收系数不同,对电磁波的吸收能力也不同,据此可分辨不同的地质构造。In order to solve problem of less information and complex detection work existed in conventional radio wave penetration method,the paper proposed a radio wave penetration method with time-domain pulsed based on impulse.It analyzed the frequency response of ideal electromagnetic pulse through a certain thickness of different media within a limited band by simulation,and draw a conclusion as follow: the radio wave penetration method with time-domain pulsed based on impulse has wider frequency range,which can increase amount of extracted information and improve detection accuracy;the electrical parameters and absorption coefficient of different medium are different,and the medium on the absorption of electromagnetic waves are different,can accordingly distinguish the different geological formations.
