Abstract

Impact of complex working environment on star sensor imaging is researched

and degradation and restoration model for blurred image is summarized and then classic Richardson-Lucy（ RL） blurred image restoration algorithms is analyzed. Aiming at the shortcoming of rining effect of the RL restoration algorithm

a modified RL restoration algorithm based on hyper Laplacian constraint factors is proposed. Simulation results indicate that the modified RL restoration algorithm can weaken the ringing effect of restoration star image and improve the quality

which lays the foundation for realization of high precision star extraction performance of star sensor affected by complex working environment.
