摘要
为了分析和研究探地雷达的地下散射问题,构建了时域有限差分法和时域矩量法相结合的混合方法,并采用该混合方法进行仿真,当散射良导体距离地面高度不同时,计算得出探地雷达接收天线中心馈电点的电流波形,通过定性和定量分析证明该混合方法所得的结果的正确性.
In order to analyze and research the scattering problem of the ground penetrating radar under the ground, a hybrid method combining FDTD and MOMTD is constructed to solve the problem. The curve of current on central feeding point of pick-up antenna is obtained by simulating when different distance between the ideal conductor and the ground is considered, correctness of the result gained by employing the hybrid method is proved through qualitative and quantitative analysis.
