Abstract: | We apply phase retrieval method to align projection data for tomographic reconstruction in reflective tomography laser radar imaging.In our experiment,the target is placed on a spin table with an unknown,but fixed,axis.The oscillatory motion of the target in the incident direction of the laser pulse is added at each view to simulate the real satellites random motion.The experimental simulation results demonstrate the effectiveness of this method to improve image reconstruction quality.Future research also includes the development of projection registration based on phase retrieval for targets with more complicated structure. |
