偏振双向反射分布函数模型研究进展

The Progress of Polarimetric Bidirectional Reflectance Distribution Function Model

对国内外偏振双向反射分布函数模型进行了归纳总结,认为:目前各个模型都依赖基于实验测量的任意角度下的穆勒矩阵,导致偏振双向反射分布函数缺乏按照电磁理论推导的物理来源。从物理本质出发,提出了未来偏振双向反射分布函数模型的发展趋势,通过理论推导研究所有影响目标偏振特性的内部本质属性和外界环境因素,找出他们对偏振特性产生影响的规律,进而揭示产生目标偏振特性的最本质原因。

The paper summarizes the pBRDF model at home and abroad, and each model relies on the Muller matrix at any angle based on experimental measurement now, which leads to the lack of physical sources for pBRDF derived from electromagnetic theory. The paper puts forward the future development trend of pBRDF model starting from the physical nature, all the internal intrinsic properties and external environmental factors that influence the polarization characteristics of the target are studied through theoretical derivation, and the law of the influence on the polarization characteristics is found out, so as to reveal the most essential reasons of the polarization characteristics of the target.
