Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

open access: yesNear Surface Geophysics, Volume 24, Issue 5, Page 669-692, October 2026.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

A reweighted matrix completion algorithm for sparse inverse synthetic aperture radar imaging

open access: yesIET Radar, Sonar & Navigation, 2023
Sparse inverse synthetic aperture radar (ISAR) imaging can be generally achieved by compressed sensing (CS) methods because sparse sampling disables the approach of conventional range Doppler. However, the CS‐based methods have to convert the matrix into

Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

New Technique for Static Target Detection in Dense-Multipath Urban Environments [PDF]

open access: yes, 2011
Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range with a finer azimuth resolution than the one provided by any on-board real antenna.

First Empirical Assessment of Ice Content From a Himalayan Rock Glacier

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Climate warming and degradation of glaciers and permafrost in High Mountain Asia is threatening the sustainability of the region's natural “water towers” and allied ecosystems and infrastructure. Approximately 25,000 Himalayan rock glaciers exist and, being more resilient to climatic change than glaciers, they represent important freshwater ...

An Autofocus Technique for High-Resolution Inverse Synthetic Aperture Radar Imagery [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2014
For inverse synthetic aperture radar imagery, the inherent sparsity of the scatterers in the range-Doppler domain has been exploited to achieve a high-resolution range profile or Doppler spectrum. Prior to applying the sparse recovery technique, preprocessing procedures are performed for the minimization of the translational-motion-induced Doppler ...

Discrimination of Truffles and Truffle Oils by a Metal–Organic‐Framework‐Based Electronic Nose

open access: yesAdvanced Sensor Research, Volume 5, Issue 9, September 2026.
A portable electronic nose based on MOF‐coated QCM sensors enables rapid authentication of truffles and truffle‐derived oils. Characteristic response patterns distinguish fresh truffle species, homemade and commercial oils, and samples adulterated with dimethyl sulfide.

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...
