Sparse regularization with a non-convex penalty for SAR imaging and autofocusing

Zi-Yao Zhang, Odysseas Pappas, Igor G. Rizaev +1

In this paper, SAR image reconstruction with joint phase error estimation (autofocusing) is formulated as an inverse problem. An optimization model utilising a sparsity-enforcing C…

SAR Image Autofocusing using Wirtinger calculus and Cauchy regularization

Zi-Yao Zhang, Odysseas Pappas, Alin Achim

In this paper, an optimization model using Cauchy regularization is proposed for simultaneous SAR image reconstruction and autofocusing. A coordinate descent framework in which the…
