A novel autofocus algorithm for synthetic aperture radar (SAR) images is presented in this paper. Based on blind deconvolution using minimum entropy criteria, the method, which starts right with complex phase degraded SAR images, carries out phase errors correction via multidimensional search. Compared with the PGA autofocus algorithm, the minimum entropy algorithm needs not isolate prominent point target in image domain and is especially suitable for the images without specific characteristic… CONTINUE READING
