High resolution SAR detection/estimation in alpha-stable interference

Ambiguity function analysis of a new design concept for side-looking synthetic aperture radar (SAR) indicates that range-rate resolution can be improved by at least a factor of ten while removing range-rate/azimuth ambiguities, and that azimuth-rate resolution can be improved by at least a factor of five. The proposed work is (1) to further verify these improvements via a realistic simulation based on actual SAR data for upwind and downwind conditions, (2) to investigate the effects of nonlinear, alpha-stable detection/estimation procedures on the improved system, and (3) to mitigate the deleterious effects that are likely to occur when nonlinear operations are applied to a system that relies heavily on linear superposition for range compression, azimuth compression, and velocity hypothesis testing operations.
