An Innovative Approach for Estimating Coseismic Surface Uplifts Using Ionospheric Observations From Remote GNSS Stations: First Application for the 2025 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The Mw 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture radars capture meters of right‐lateral displacements but isolating vertical ...

EXPERIENCE OF RADAR DATA PROCESSING FOR GEOGRAPHIC MAPPING

InterCarto. InterGIS, 2014
New synthetic aperture radar (SAR) systems suggest new potentials for the environmental studies and mapping due to high spatial resolution, various beam modes and the full polarization mode. Current level of imaging radar development together with amount

Water Storage Capacity Dynamics in Drained Boreal Peatlands: Responses to Rewetting and Climate Change

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Historical peatland drainage resulted in surface subsidence and reduced water storage capacity (WSC), a process that can be exacerbated by climate change. We assessed the effects of rewetting on WSC using mesocosm experiments in climate chambers, field measurements, and Interferometric Synthetic Aperture Radar (InSAR) analysis.

Nonlinear Release of Subinertial Diurnal Internal Tides Forms Spiral Internal Solitary Waves

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Earth's rotation imposes a dynamical barrier on the free propagation of internal tides at high latitudes, raising questions about the fate of tidal energy poleward of the critical latitude. Satellite observations reveal spiral internal solitary waves (ISWs) along the continental slope of the South Orkney Plateau.

Digital Beamforming and MIMO SAR: Review and New Concepts [PDF]

, 2012
Spaceborne Synthetic Aperture Radar (SAR) is a unique tool for large scale Earth observation, but the current generation of SAR sensors suffers from some fundamental limitations with regard to their imaging and mapping capabilities.

Interferometric baseline performance estimations for multistatic synthetic aperture radar configurations derived from GRACE GPS observations [PDF]

, 2006
Recent studies have demonstrated the usefulness of global positioning system (GPS) receivers for relative positioning of formation-flying satellites using dual-frequency carrier-phase observations. The accurate determination of distances or baselines

BridgeSAR: Measuring Bridge‐Water Clearance From Space Using SAR Multipath Signatures

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Bridge‐water clearance controls safe vessel passage and reflects local water‐level changes, but direct measurements are unavailable at many bridges. We present BridgeSAR, a geometry‐guided method that estimates clearance from multipath scattering stripes in synthetic aperture radar (SAR) amplitude images.

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.
