A Simulation Algorithm of The Space-based Optical Star Map with Any Length of Exposure Time

Aiming at the particularity of star tailing imaging under long exposure time, a simulation algorithm of the space-based optical star map with any length of exposure time is proposed. Firstly, the imaging process of the real space-based optical star map is introduced, and the imaging simulation process is designed. Then, by analyzing the limitations of traditional star tailing simulation algorithms, a star tailing simulation algorithm that adapts to long exposure time is proposed. And realized the simulation of space-based optical star map with any length of exposure time. The simulation experiment results show that this algorithm can simulate the star tailing images with any length of exposure time while ensuring the fidelity of imaging, which is of great significance to the development of space-based optical detection platforms.
