Ocean Oil Spill Classification with RADARSAT-2 SAR Based on an Optimized Wavelet Neural Network
Remote Sensing, 2017 Oil spill accidents from ship or oil platform cause damage to marine and coastal environment and ecosystems. To monitor such spill events from space, fully polarimetric (Pol-SAR) synthetic aperture radar (SAR) has been greatly used in improving oil spill

Enhancing SAR Ship Image Generation With Context‐Guided Upsampling in DDGAN
Electronics Letters, Volume 62, Issue 1, January/December 2026.To address the scarcity of high‐quality training data for SAR ship detection, this paper proposes a novel image generation method based on an enhanced denoising diffusion generative adversarial network. The core innovation is a context‐aware upsampling filter designed to preserve structural details and suppress artifacts during image synthesis ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

Multi-baseline Pol-InSAR Forest Height Estimation in the presence of temporal decorrelation [PDF]
, 2010 Polarimetric Synthetic Aperture Radar (SAR) Interferometry (Pol-InSAR) is a radar remote sensing technique, based on the coherent combination of radar polarimetry (Pol-SAR) and SAR interferometry (InSAR) which is substantially more sensitive to ...

Space-borne polarimetric SAR sensors or the golden age of radar polarimetry
EPJ Web of Conferences, 2010 SAR Polarimetry represents an active area of research in Active Earth Remote Sensing. This interest is clearly supported by the fact that nowadays there exists, or there will exist in a very next future, a non negligible quantity of launched ...
