中文摘要： 针对偏振光模式在大气中产生与传输的相关科学问题，以光与大气相互作用的物理过程为研究对象，以信息的产生与传输为主线，以米氏散射、矢量辐射传输理论、Markov链统计特性理论为理论基础，按照科学研究趋势与应用需求，研究偏振光模式产生与传输中的统计特性问题，形成具有Markov链统计特性的偏振光模式基础理论与研究方法。研究偏振光模式产生与传输中的可计算性问题，减少实际模型计算过程对硬件和时间资源的需求，形成可实现的3D大气层内偏振光模式的计算与仿真理论。在此基础上，在计算模型中将参数从标量向矢量拓展，将空间从2D向3D拓展，将范围从时不变向时变拓展。解决多因素影响下的非球形粒子散射问题、粒子集群散射问题及偏振模式产生问题、偏振光模式在3D大气层内的可计算问题与时变传输等关键问题。本课题将建立实际的大气偏振模式与传输模型，为偏振光模式的实际应用打下理论基础。

英文摘要： To solve related scientific issues induced by polarized-light pattern's generation and transmission in the atmosphere, we focus on the study of physical interactions between sunlight and atmosphere by following the origin and transfering of information. Taking the Mie scattering theory, radiative transfer theory and the Markov Chain statistics as theoretical background, we mainly study the statistical properties in polarized-light pattern's generation and transmission and establish correlative theoretical and technological foundations with the Markov Chain characteristics. To build an realizable models for polarized-light pattern's computations and simulations in 3D atmosphere, we also focus on studying the related computable issues and reduce the time and harware consumption in the computing progress. On these bases the computing model expands parameters from scalar to vector, space from 2D to 3D and time domain form invariant to variable. In the project the key issues to be solved including non-spherical particles's scattering under various conditions, particle cluster's scattering,the polarized-light pattern's generation and the computable and time-variable issues. We will build realistic polarized-light pattern theory system and transmission model and provide theoretical foundation for the application.
