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.
