Abstract

When the satellite was swinging and taking lateral imaging, the TDI CCD pixel photovoltaic charge purses transferred velocity not matched with the image motion velocity. According to the requirement of high-resolution satellite which was taking lateral imaging at a low orbit, the factors that bring about the unmatched phenomenon were analysed, inclusive of the Earth´s rotation, the Earth curvature, satellite attitude change , measurement error and the installation error, etc. Image motion errors caused by various factors were analysed and solved, and the different characters of image motion errors were synthesized. Finally, the total errors on the impact of imaging system MTF was analyzed.
