摘要
对探地雷达的微波全息成像 (MHI)法进行了分析研究 ,根据有耗介质空间中的εr 对脉冲传播速度的影响 ,以及对脉冲在收发天线与目标之间的往返时间的影响指出 :可将有耗介质空间转化到自由空间 ,再将自由空间中的计算结果修正到有耗介质空间 .
The method of subsurface radar's MHI is described in this paper. According to the effect of relative permittivity εr on the pulse propagation velocity in lossy dielectric space and the effect on the turnround time of signal between the antenna and the buried objects, it is presented that lossy dielectric space can be transformed into free space and the simulation results abtained from free space can also be amended to lossy dielectric space. Several examples in this paper demonstrate the viability and accuracy of the amending method.
