%X Due to the special operation mode of TDI CCD, image shift is resulted from earth self_rotation in polar orbit sensing. This kind of image shift makes image degradation, resolution decrease, and target margin mistiness. Compensating the shifted image is an important problem that must be resolved in the application of polar orbit satellite TDI CCD camera. In this paper, the image shift of TDI CCD camera for polar orbit satellite is forecasted, then the effect of image degradation is calculated. A mathematical model is set up according to the principle of TDI image shift, and an image compensation filter is worked out, which is proved to be valid by computer simulation.
