摘　　要：太阳光通过大气层时会与大气粒子间发生相互作用从而产生偏振光,天空中各种不同属性的偏振光叠加,便形成了包含大气信息参数在内的各种信息的大气偏振模式分布。文章研究了太阳光散射形成的大气偏振特性,分析了基于蒙特卡洛理论的仿真方法,在实现大气偏振模式仿真的基础上,将实际检测结果与理论仿真模型进行对比分析,验证了该方法的正确性。When the sunlight is going through the atmosphere,it will interact with atmospheric particles to produce polarization light,and the superposition of various kinds of polarization light in the sky will develop the atmospheric polarization mode containing atmospheric information parameter and so on.The atmospheric polarization characteristic formed by scattering sunlight and the modeling method of the atmospheric polarization based on Monte Carlo modeling of light transport（MCML） are analyzed in this paper.The comparative analysis of testing results and those of theoretical simulation model verifies the correctness of the presented method.
