CauchySAR_v1

This software includes MATLAB source code for solving SAR imaging inverse problems using the Cauchy proximal splitting (CPS) algorithm. CPS is a method for the optimization of a cost function that includes a non-convex Cauchy-based penalty. The convergence of the overall cost function optimization is ensured through careful selection of model parameters within a forward-backward (FB) algorithm. The package includes solutions to three standard SAR imaging inverse problems, i.e. super-resolution, image formation, and despeckling, as well as ship wake detection for maritime applications.
