Abstract

Multi-frame blind deconvolution (MFBD) has been shown to be useful for overcoming the blurring effects of turbulence- and instrument-induced aberrations in ground-based imaging of satellites. In this scenario, the object has a finite extent that is often entirely contained within the sensor field-of-view. We report on the generalization of MFBD to accommodate objects that extend beyond the field of view, as would be encountered, for example, in solar and planetary astronomy or in down-looking scenarios. We simulate both down-looking and up-looking scenarios, and vary parameters such as the level of scene illumination and the number of data realizations included. In the simulations, MFBD performance is evaluated by comparing results to the true scenes as well as to reconstructions using more established Phase-Diverse Speckle techniques. Using real data, MFBD reconstructions of solar-granulation scenes are validated by comparison with well-accepted PDS results.
