摘　　要：大气辐射校正是定量遥感的基础性工作,大气校正效果的优劣直接决定后续定量遥感分类和参数反演的精度。文中通过对模拟的多光谱遥感影像数据比较FLAASH和ATCOR两种常用的大气校正方法,以评价二者大气校正效果。Atmospheric radiation correction was the basic work of quantitative remote sensing,the merits of the atmospheric correction directly determined the accuracy of the subsequent quantitative remote sensing classification and the parameter inversion. In the paper,two commonly used atmospheric correction methods,FLAASH and ATCOR,were compared,by the simulated multispectral remote sensing image data to evaluate the effect of atmospheric correction.
