非共面几何条件下的非视线极化单散射传播模型
Non-line-of-sight polarized single-scatter propagation model for noncoplanar geometries
摘要：
经典的非视线（NLOS）单散射面共面传播模型最近被扩展到包括非共面几何，扩展模型中的计算过程部分基于笛卡尔坐标系，并且有些复杂。提出了一种新的非共面几何条件下的非视距单散射传播模型，该模型仅基于长椭球坐标系，可以看作是上述扩展模型的简化版本。与基于蒙特卡罗的多散射模型的偏振扩展相似，新的非共面几何结构的单散射模型也被扩展到考虑偏振;偏振单散射模型被基于蒙特卡罗的偏振模型验证，结果显示完全匹配。基于偏振单散射模型，验证了双偏振紫外光通信链路的理论可行性。
英文摘要：
The classical model of non-line-of-sight (NLOS) single-scatter propagation for coplanar geometries was recently extended to include noncoplanar geometries; the calculation processes in the extended model are partly based on the Cartesian coordinate system and are somewhat complicated. A new NLOS single-scatter propagation model for noncoplanar geometries is presented based only on the prolate spheroidal coordinate system, which can be considered as the simplified version of the extended model mentioned above. Similar to the polarization-extension of the Monte-Carlo-based multiple-scatter model, the new single-scatter model for noncoplanar geometries is also extended to take polarization into account; the polarized single-scatter model is validated by the Monte-Carlo-based polarized model, results show perfect match. The theoretical feasibility of a 2-polarization UV communication link is validated based on the polarized single-scatter model.
