document: Supersampling multiframe blind deconvolution resolution enhancement of adaptive optics compensated imagery of low earth orbit satellites We describe a postprocessing methodology for reconstructing undersampled image sequences with randomly varying blur that can provide image enhancement beyond the sampling resolution of the sensor . This method is demonstrated on simulated imagery and on adaptive-optics - -LRB- AO -RRB- - compensated imagery taken by the Starfire Optical Range 3.5-m telescope that has been artificially undersampled . Also shown are the results of multiframe blind deconvolution of some of the highest quality optical imagery of low earth orbit satellites collected with a ground-based telescope to date . The algorithm used is a generalization of multiframe blind deconvolution techniques that include a representation of spatial sampling by the focal plane array elements based on a forward stochastic model . This generalization enables the random shifts and shape of the AO-compensated point spread function -LRB- PSF -RRB- to be used to partially eliminate the aliasing effects associated with sub-Nyquist sampling of the image by the focal plane array . The method could be used to reduce resolution loss that occurs when imaging in wide-field-of-view -LRB- FOV -RRB- modes
