摘要

摘要: 该文给出了一种利用时域有限差分法(FDTD)，结合各向异性完全匹配层(UPML)以及互易原理，计算地下目标雷达散射截面的计算方法。通过数值实验，对这种计算方法的数值性能作了仔细研究。给出了一批新的不同电尺寸、不同形状、不同介电常数地下目标的雷达散射截面计算结果。

Abstract: A computation approach of scattering by buried objects is presented by using Finite-Difference Time-Domain (FDTD) method, the Uniaxial Perfectly Matched Layer (UPML), and reciprocity principle. The numerical performance of this approach is in detail investigated by numerical experiments. The Radar Cross Section (RCS) of various buried objects with different electrical size, shape, dielectric constant, are computed and analyzed, from which useful conclusions are obtained.
