模型分析及测试方法计算大气调制传递函数
Calculating atmospheric modulation transfer function with model analysis and measurement
摘要
Abstract
Two methods of calculating atmospheric modulation transfer function (MTF) are introduced, which are model analysis based on point spread function and MODTRAN software calculation based on measured parameters. The model of atmospheric MTF was modified by introducing the influence of atmospheric stratification and a calculation about the structure constant of atmosphere refractive index fluctuations. All the parameters and calculation methods required in the model are presented. The methods for calculating these parameters are provided. A method of calculating MTF by MODTRAN is introduced. The parameters that influence the MTF are analyzed by simulation based on the working environment of airborne ima-ger. Therefore, the influence of atmospheric environment on it can be evaluated.关键词
