Abstract
Star image blurred by aircraft vibration decreases location accuracy and probability of the star extraction. In this paper, first, the influence of aircraft vibration on the star image captured by star sensors is analyzed, and the mathematical model is deduced and established. Then, in order to overcome the adverse effects of star extraction and stabilize the accuracy of star sensor in high dynamic environment, a restoration method for blurred star image using Richardson-Lucy (RL) method is introduced. The experimental results indicate that the proposed method can effectively improve the star image signal-to-noise ratio and the extraction accuracy.
