Abstract : This research program investigated signal processing problems encountered in high- resolution image formation. Reliable imaging of scenes with high resolution and high speed is an important and key part of any defense system. In some imaging systems, the image has to be constructed from linear measurements and convex constraints(such as upper and lower bounds on image sample magnitude, and support limits). studied iterative, finite parameter reconstructions that lead to images that meet constraints, match the data to within a pre-specified tolerance, and come closest to a given nominal. e addressed three different aspects of signal/image reconstruction, namely, (1) Developing fast algorithms for high resolution signal/image reconstruction, (2) Resolutions Analysis of signal reconstruction algorithms, (3) Numerical and computational aspects of signal reconstruction viz: stability and regularization.
