Satellite high resolution imaging simulation in space field

In the paper, a new satellite image simulation method in space field is proposed. According to the path of the satellite imaging transmission, the simulation is divided into three parts: atmosphere transmission simulation, optical system imaging simulation, and CCD sampling, integral and quantizing simulation. The experiment results show that the simulation method in space field can get images closer to reality than the simulation based on MTF, which provide the detail effects on the imaging path from ground to CCD, and could be an effective tool to estimate the image quality before satellites in orbit.
