1. A method for creating a high spatial resolution image from a multidimensional imagery, the method comprising: obtaining a baseline image from the multidimensional imagery; deriving n×m−1 sub-pixel shifted images from the multidimensional imagery, where n and m are integers and greater than 1; organizing the baseline image and the n×m−1 sub-pixel shifted images from the multidimensional imagery; fusing the organized images using iterative back projection (IBP) to generate a high resolution image; and outputting the generated high resolution image.
