本文利用四元极化SAR数据，对简单二面体结构进行极化散射分析，以实现对洪水泥流损坏的人造物体的精确检测。利用时域有限差分（FDTD）方法进行分析。二面体模型由薄的完美导电体 (PEC) 板组成。将具有缓坡的介电板设置在其中一块 PEC 板上，模拟泥流中的湿土。详细研究了偏振散射对覆盖电介质条件变化的依赖性。
In this paper, we carry out polarimetric scattering analysis for simple dihedral structure, to realize accurate detection of manmade object damaged by flood-related mudflow, using quad polarimetric SAR data. The Finite Difference Time Domain (FDTD) method is utilized for the analysis. The dihedral model is composed of thin perfectly electric conductor (PEC) plates. Dielectric slab with gentle slope, which simulates wet soil in mudflow, is set on one of the PEC plates. The dependency of the polarimetric scattering on change of condition of the covered dielectric is investigated in detail.
