The Modulation Transfer Function (MTF) is an important comprehensive evaluation index for the performance of the optical imaging system and also the most important part of image degradation model. According to the characteristics of TDI-CCD image data,this paper discussed the ways of calculating MTF of the image system based on the edge detection in remote sensing image,and implementing MTF compensation to the degradation image with winner filter and modified inverse filter (MIF) respectively. The results show that the adaptive MTF restoration processing method can effectively improve image quality of high resolution TDI-CCD image data. At present,this method has been successfully applied to the domestic ground satellite pre-processing system in China.
