Study on imaging simulation of telescopefor space target

The imaging process of the telescope is studied through numeric simulation; the lay tracking modeling of this process is established through the lay tracking theory. Based on the linearity strain-wave theory, the MTF of every buildup unit in the imaging system is analyzed and presented; the MTF modeling is also established. Combining the lay tracking modeling and the MTF modeling, a physics modeling of the telescope for space target is established, the simulation flow is presented. the simulation model is studied and carried out, and the gray curve, theory MTF and the image is presented, which proved that the model is reasonable.
