天气怎样影响成像

How the weather influence imaging

文中讨论了低层大气层的光学成像问题，着重阐述了各种大气效应对成像质量的影响。按照成像的流程把大气效应的入射辐射与表面反射分开考虑，得到了气象参数与物体表面辐照度的关系，以及气象参数与成像对比度和分辨率的关系。最后通过实验模拟了不同天气条件下的场景成像。

The issue of optical imaging in low level of atmosphere is discussed in this paper, with emphasis on the influence of various atmospheric effects on the quality of imaging. The effects can be divided into two parts, incidence irradiance and reflecting radiance, according to the flow of imaging. Therefore, the relationship of weather parameters and surface irradiance is got, as well as image contrast and resolution. The experiments to simulate the scene imaging under various weather conditions are presented.\=\;
