Abstract

A 3-D finite difference time domain (FDTD) simulation is done on a ground penetrating radar (GPR) operating above lossy and dispersive grounds. The radar consists of a pair of resistor-loaded bow-tie antennas and the ground consists of Puerto Rico clay loam. The clay loam is modeled by using a two term Debye model with a static conductivity. The simulation results show the GPR response of buried metal and plastic pipes. The results are more realistic as the simulations include commercially used antennas and real ground conditions. The target signatures and target polarization characteristics of the pipes are also studied in the paper

探地雷达在有损和色散地面上的全三维模拟

对工作在有损和色散地面上的探地雷达进行了三维时域有限差分仿真。雷达由一对负载电阻的领结天线组成，地面由波多黎各粘土壤土组成。采用具有静态电导率的两项德拜模型对粘土壤土进行了建模。仿真结果显示了埋地金属和塑料管的探地雷达响应。由于模拟包括了商用天线和真实地面条件，结果更加真实。本文还对管道的目标特征和目标极化特性进行了研究
