IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This work proposes a conditional diffusion model framework for high‐fidelity 3D reconstruction from sparse multibaseline circular synthetic aperture radar (CSAR) data, addressing challenges of low vertical resolution, geometric blur and artefacts. The method integrates a dual‐path 3D U‐Net with cross‐attention to fuse coarse reconstruction features ...

3D Point Cloud Reconstruction Using Inversely Mapping and Voting from Single Pass CSAR Images
Remote Sensing, 2021 3D reconstruction has raised much interest in the field of CSAR. However, three dimensional imaging results with single pass CSAR data reveals that the 3D resolution of the system is poor for anisotropic scatterers.

The Unexploited Treasures of Hydrological Observations Beyond Streamflow for Catchment Modeling
WIREs Water, Volume 12, Issue 2, March/April 2025.Caption: In situ and satellite‐based observations of hydrological variables beyond streamflow are valuable to improve modeling catchment hydrology (modified from Fisher 2005; CC BY‐SA 4.0). ABSTRACT While measured streamflow is commonly used for hydrological model evaluation and calibration, an increasing amount of data on additional hydrological ...
