墙体中金属细导体目标的电磁散射特性研究
摘要:
建立了建筑物墙体结构探测雷达的物理模型,提出了一种墙体中金属细导体目标散射的偶极子源计算方法,利用分层介质中偶极子公式结合边界条件和矩量法得到了墙体中金属细导体在墙外任一点的散射场强度,并将计算结果与时域有限差分数值模拟结果进行了比较,结果表明该方法能够实现对墙体中金属细导体目标散射场的快速计算和分析,可以为墙体结构探测雷达成像和电磁学反演方法提供一种快速算法.
A physical model for the detection radar of the wall structure is established.Numerical computational method of electromagnetic scattering by slim metal conductor buried in the wall is proposed through the dipole method,and the scattering field is derived by boundary conditions combined with MOM.Then the results between the calculations and finite difference time domain method are compared.It shows that this method can calculate and analyze the electromagnetic scattering of the slim metal conductor buried in the wall quickly,and provide a fast algorithm to the detection radar imaging and electromagnetism inversion calculation.
