摘　　要：文章首先针对中巴地球资源卫星的CCD成像系统的成像原理,提出基于调制传递函数(MTF)的遥感图像校正方法;其次,通过实验,使用均值、标准方差以及边缘能量等指标对MTF复原方法的结果进行了比较;最后,对影响MTF校正品质重要因素的噪声进行分析与讨论。Firstly, the remote images correction method was proposed based on MTF according to photograph principle of CBERS- 01/02 CCD camera; secondly, the results of decayed image and the MTF correction image were compared through image indexes; finally, the noises, which influenced the images＇ quality, were analyzed in several aspects.
