Assessing SWOT's Measurement Capabilities in the Complex Paraná River

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Estimating water surface elevation (WSE) is crucial for understanding hydrological processes; however, many rivers remain insufficiently monitored due to the limitations of in situ gauge networks. The Surface Water and Ocean Topography (SWOT) mission, equipped with Synthetic Aperture Radar technology, enables global monitoring of WSE with high

Dam Regulation Moderates Climate‐Induced Rice Yield Loss in the Mekong‐Tonle Sap Lake System

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Rice, a principal global staple crop, is increasingly threatened by flooding under climate change, placing rice‐dependent economies at risk. Yet the capacity of human activities to mitigate inundation impacts on rice remains insufficiently quantified.

Advanced Unsupervised Classification Methods to Detect Anomalies on Earthen Levees Using Polarimetric SAR Imagery

Sensors, 2016
Fully polarimetric Synthetic Aperture Radar (polSAR) data analysis has wide applications for terrain and ground cover classification. The dynamics of surface and subsurface water events can lead to slope instability resulting in slough slides on earthen ...

Intra‐Tessera Plains: Implications of Their Radar Properties for Surface Processes on Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Intra‐tessera plains are radar‐dark plains deposits that occur within tesserae. Their emplacement mechanism(s) and composition are poorly constrained, though they are hypothesized to be basaltic lava flows. Here, we map intra‐tessera plains within 16 different tesserae spanning various latitudes and elevations.

Design of a millimetre Synthetic Aperture Radar (SAR) onboard UAV's

2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
This paper describes the design for an experimental short-range (2 Km) high-resolution (30 x 30 cm²) synthetic aperture radar (SAR) sensor in the millimetre wave band to take it onboard unmanned aerial vehicles (UAV). The novelty lies on the establishment of new and very demanding requirements induced by the need of being onboard low cost aerial ...

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...
