| Abstract: | This paper deals with the analysis of influence on imaging of orbit perturbation and structure deformation based on earth-satellite integrated compensation. Firstly, azimuth and elevation, as well as fixed grid are defined according to the target of image registration. Secondly, compensating schemes and models are designed for the image motion compensation. Finally, simulation results show that the proposed schemes can efficiently reduce the optical axis disturbance for the scanning mirror due to the satellite orbit perturbation and structure deformation, and meet the primary specification requirement of the image registration. |
