Paper Abstract

We present an improved regularized pseudo inverse method that can super-resolve passive imagery. The algorithm is a non-iterative technique that involves convolution operations in the spatial domain which allows an image to be processed in the frame time of the imager. Our method gives encouraging results, providing a significant increase in spatial resolution with only a small reduction in the final signal to noise ratio. Examples are given of the application of the technique to millimeter-wave (mm-wave) images and a comparison is made with other fast deconvolution methods and computer intensive super-resolution algorithms. Finally, a brief discussion is given of how high speed hardware is used to implement this algorithm.
