【摘要】 针对现有大气偏振模式理论模型单独考虑太阳或月亮的影响，无法充分描述晴朗天气下黎明和黄昏过渡期间天空偏振模式的问题，提出了一种曙暮光影响的大气偏振模式建模方法。该方法引入太阳和月亮的影响，以太阳和月亮位置求解的Stokes矢量为基础，同时考虑了实际天空中大气粒子多次散射的因素，对Stokes矢量优化；分析太阳和月亮对大气偏振模式的影响，确定了太阳和月亮的影响权重；利用偏振角表征大气偏振模式。结果表明，所提模型的仿真结果与实测偏振角具有相同的分布和变化特性，且保持着较高的相似度，能够有效地表征曙暮光影响的大气偏振模式。更多还原

【Abstract】 Existing theoretical models of skylight polarization patterns have problems that only consider the influence of the sun or the moon alone and could not adequately describe the polarization patterns of the sky during the transition between dawn and dusk in clear weather. Therefore, a modelling method of skylight polarization patterns under the influence of twilight is proposed. The method introduces the influence of the sun and the moon and calculates the Stokes vectors using the position of the sun and the moon. Considering the factors of multiple scattering of atmospheric particles in the actual sky, the influence weights of the sun and the moon are determined by Stokes vector optimization. In addition,the obtained angle of polarization is used to characterize the skylight polarization patterns. The experimental results show that the simulation results of the proposed model and the measured angle of polarization have the same distribution and variation characteristics, and maintain a high degree of similarity, which can effectively characterize the skylight polarization patterns influenced by twilight.更多还原
