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…

Ship Wake Detection in SAR Images via Sparse Regularization
Oktay Karakuş, Igor Rizaev, Alin Achim
In order to analyse synthetic aperture radar (SAR) images of the sea surface, ship wake detection is essential for extracting information on the wake generating vessels. One possib…
