摘要
在用遥感影像反演地面参数时,即使天气晴朗,也要受大气、气溶胶、云的影响。因此大气校正成为提高反演精度的 主要因素之一,文中在介绍大气传输的概念模型的基础上,对遥感影像的大气校正方程和参数做了介绍,同时介绍了怎样用 MODTRAN获取这些参数,并做了具体分析。
When using the remote sensing images to reverse the land parameters, the results may he influenced by the atmosphere, aerosol and clouds etc. even if in the sunshine. Therefore the atmospheric corrections serve as one main factor for raising the accuracy of the reversion. This paper introduces the equations and parameters of the atmospheric corrections for remote sensing images on the basis of introducing the conceptual model of the atmospheric transmission, and at the same time describes how to use the MODTRAN to gel these parameters, and concrete analysises are finally made.
