Abstract More and more modern high resolution optical remote sensing satellites are being equipped with TDI CCD cameras. Modulation Transfer Function (MTF) is an authoritative means in evaluating the quality and implementation capability of the imaging system. For the purpose of evaluating the satellite criteria in the phase of production, it is necessary to simulate images with the satellite MTF criteria in enough reality. Based on a detailed analysis of the relationship between the satellite criteria and the on-orbit satellite TDI CCD imaging degeneration, this paper gives a method for the simulation of the degeneration process. With the method, a soft ware system was built to simulate the on-orbit imaging process of the designed satellite, which can provide the application experts with a powerful tool to judge the satellite in designing and production.
