Sparse Regularization with a Non-Convex Penalty for SAR Imaging and Autofocusing

Sparse Regularization with a Non-Convex Penalty for SAR Imaging and Autofocusing

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 Cauchy regularizer is proposed, and an alternating minimization framework is used to solve it, in which the desired image...
