Abstract
The star image obtained by star sensor is blurred when spacecraft makes rapid maneuver.Based on Wiener filtering,a star image restoration algorithm is proposed.The influence of blur parameters on the accuracy of star centroid estimation is analysed.The comparison data of star centroid estimation accuracy and attitude estimation accuracy of blurred star image and restored star image are obtained through extensive experiments.Simulation results show that the restored star image can significantly improve the accuracy of star centroid estimation and attitude estimation,and effectively improve the success rate of star image recognition.
