Learning to Optimise FISTA‐PnP for Sparse Radar Imaging

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This work presents a plug‐and‐play (PnP) framework for sparse radar imaging that combines FISTA with reinforcement learning (RL)‐based parameter adaptation, achieving faster convergence and eliminating manual parameter tuning. Extensive experiments show the framework outperforms classical methods and recent optimisation networks, providing high‐quality

Hyperspectral Imaging: The Intelligent Eye to Uncover the Password of Plant Science

open access: yesModern Agriculture, Volume 3, Issue 2, December 2025.
Hyperspectral imaging (HSI) has emerged as a powerful non‐destructive technique for characterisation of the plant phenotype and physiological traits. The ongoing development of cost‐effective hardware, coupled with standardised acquisition protocols and open‐access spectral libraries, is accelerating its integration with multi‐omics approaches to ...

Rethinking Global Soil Degradation: Drivers, Impacts, and Solutions

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The increasing threat of soil degradation presents significant challenges to soil health, especially within agroecosystems that are vital for food security, climate regulation, and economic stability. This growing concern arises from intricate interactions between land use practices and climatic conditions, which, if not addressed, could ...

Rapid Methane Flux Estimation Combining MethaneSAT and Sentinel‐5P Observations: A Case Study of Turkmenistan

open access: yesGeophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Rapid estimation of high‐resolution (∼km), regional‐scale (∼104 km2) CH4 fluxes plays a critical role in supporting the Global Methane Pledge and guiding targeted mitigation strategies. This study presents a novel method that combines XCH4 observations from MethaneSAT and Sentinel‐5P to directly estimate CH4 fluxes without relying on chemical ...

Object-Level Semantic Segmentation on the High-Resolution Gaofen-3 FUSAR-Map Dataset

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Land cover classification with SAR images mainly focuses on the utilization of fully polarimetric SAR (PolSAR) images. The conventional task of PolSAR classification is single-pixel-based region-level classification using polarimetric target ...

Quantifying the Lifespan of 3D Flood Structures: Unlocking the Potential of Flood Detention Areas for Enhanced Flood Control in China

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract The escalating frequency and magnitude of floods pose significant challenges to traditional flood control measures with fixed defense capacities, such as levees, dams, and reservoirs. Flood Detention Areas (FDAs) have been widely implemented in many countries as solutions to extreme flood events, functioning by temporarily holding excess ...

Asymmetry of Cyclonic Sea Surface Wind and Wave Observed by SAR

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract CyclObs‐derived wind and SWH field are extracted from over 600 dual‐polarized Sentinel‐1 (S‐1) images of around 300 tropical cyclones (TCs) over the past eight years to investigate asymmetry of wind and wave fields during TCs. Fetch analysis and machine learning technique, eXtreme Gradient Boosting (XGBoost), is used to establish a ...

The GF-3 SAR Data Processor

open access: yesSensors, 2018
The Gaofen-3 (GF-3) data processor was developed as a workstation-based GF-3 synthetic aperture radar (SAR) data processing system. The processor consists of two vital subsystems of the GF-3 ground segment, which are referred to as data ingesting ...
