摘要
Atmospheric polarization pattern contains a plenty of informations, such as informations of the spatial orientation, characteristics of earth's surface, structure parameters of the atmosphere, et al, which has important research value in polarotactic navigation, remote sensing, and other fields. However, the real celestial polarization pattern in the turbid atmosphere is quitely different from simulation results of existing classical models, which cannot represent the atmospheric polarization pattern in turbid atmosphere. A turbid simulation model of atmospheric polarization pattern is proposed. This new model can be set up by using the three dimension (3D) celestial sphere model to describe the real atmosphere, using the Monte Carlo program of polarized light transport to simulate radiation transfer of the sunlight in the atmosphere. The experiments show that this model is consistent with the real polarization pattern in turbid atmosphere. Specifically the degree of polarization distribution highly accords with the real degree of polarization distribution. And the angle of polarization distribution can reflect the distribution and change feature of the real angle of polarization accurately. In conclusion, this model can be used to analyze and predict the distribution and change feature of the real atmospheric polarization pattern in turbid atmosphere.
