Abstract :
The author derives an estimate-maximise (EM) formulation of a Bayesian super-resolution algorithm for reconstructing scattering cross sections from coherent images. He generalises this result to obtain an autofocus/super-resolution method, which simultaneously autofocusses an imaging system and super-resolves its image data. Autofocus/super-resolution might be applied to the interpretation of airborne synthetic aperture radar images that are subject to defocussing effects
