由于受到大气的影响,传感器接收到的辐射信息不能真实地反映地表反射光谱信息,因此,从遥感影像中去除大气的影响,即进行大气校正,是高光谱遥感数据处理中极为重要的环节。文章介绍了EO-1hyperion高光谱数据的特点,以及用FLAASH(Fast Line of Sight Atmospheric Analysis of Spectral Hyper-cubes)模块对新疆地区Hyperion高光谱遥感影像进行大气校正,并对处理结果进行评价,结果表明FLAASH模块大气纠正效果良好。

Due to the effect of atmosphere on the earth,the radiometric energy which acquired by the remote sensor do not directly represent the reflectance spectrum of the surface materials.Therefore,removing atmospheric effects on the imagery,a process known as atmospheric correction,is a quite important part for the hyper-spectral remote sensing.This paper introduces the characteristics of EO-1hyperion high spectrum data,the FLAASH atmospheric correction is performed with a scene of Hyperion over the Xinjiang area.The processing results are appraised,the results indicate that the correction is good.
