装有金属引信的埋地介质地雷电磁散射计算

Scattering from Buried Dielectric Landmine with Metal Fuze

本文由等效原理推导了埋在有耗、色散土壤中的装有引信的介质地雷的电磁场积分方程,根据地雷的旋转对称特性,利用矩量法计算了半空间地雷的电磁散射,并与车载地表穿透SAR的实测数据进行了对比,两者比较一致,验证了计算方法的有效性。

This paper analyses scattering from dielectric landmines with metal fuze buried in a lossy, dispersive half space using equivalent theory. The calculations are performed using a Method of Moments (MoM) algorithm for bodies of revolution. In the end, this paper compares the theoretical results and the experimental results collected by the vehicle-mounted ground penetrating synthetic aperture radar (GP-SAR). The agreement is good, which shows that the algorithm is efficient.
