用基于遥感器辐射定标参数和大气辐射传输模型计算的方法对CBERS-02卫星CCD图像进行了大气订正，较好地消除了CCD遥感图像中非目标地物的成像信息。为了消除目标邻近像元的影响，假定目标是处在某一特定反射率的大尺度参考背景下，然后再将反射率修正到实际背景中，通过这种方法获得的大气订正图像的细节部分更加清晰，对比度增强，大大改善了CCD图像的质量。

The method,which is based on the radiometric calibration coefficient and the atmospheric radiative transfer software,is used to atmospheric correction of CBERS- 02's CCD image.The non-object information has been removed from the CCD remote sensing image.In order to eliminate adjacent effect,it is supposed that the object is in a large scale reference background which has a certain reflectance.And then it is adapted to the actual background.By using this method,the corrected image whose detailed part is much clear than the uncorrected,has been enhanced.
