中文摘要：

后向散射穆勒矩阵仿真应用的研究具有很多潜在的优势,通过分析穆勒矩阵元素传递的信息可以有效辨别介质特性。以大气环境介质为探究背景,通过偏振蒙特—卡洛仿真方法建模,分析了不同大气环境介质情形下,穆勒矩阵元素的变化规律。仿真结果表明：随介质粒子尺寸增加,穆勒矩阵元素整体呈现向中心收缩态势,特定元素对粒子尺寸敏感,其径向峰值可以明显反映粒子尺寸变化;随介质粒子浓度增加,穆勒矩阵元素强度衰减,特定元素圆周曲线幅值可以反映粒子浓度变化。

英文摘要：

Backscattering Muller matrix simulation is widely used in many tasks.By analyzing information of Mueller matrix elements,atmospheric medium properties can be distinguished.To investigate atmospheric environment medium,use Monte Carlo modeling to simulate the variation rule of Mueller matrix with respect to different atmospheric medium.The simulation results show that,with the increasing of particle size,Mueller matrix elements come to the center.As Muller matrix elements are sensitive to particle size,radial peak of specific elements can clearly reflect the changes of particle size.With the increasing of medium particle concentration,elements intensity of Mueller matrix weakens,amplitude of specific elements can reflect the changes of particle concentration.
