Hyper-parameter selection in non-quadratic regularization-based radar image formation [PDF]
, 2008 We consider the problem of automatic parameter selection in regularization-based radar image formation techniques. It has previously been shown that non-quadratic regularization produces feature-enhanced radar images; can yield superresolution; is ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Simultaneous analyses of complementary GNSS and InSAR measurements may lead to breakthroughs in our understanding of crustal deformation. We present an algorithm that combines InSAR with GNSS measurements, in which the GNSS data can be used either as original station velocities or as an interpolated and smoothed velocity field, to estimate ...

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.Abstract Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide‐generated seismic and infrasound (low‐frequency atmospheric sound) waves can be remotely detected in near real‐

Remote Sensing Data Assimilation With a Chained Hydrologic‐Hydraulic Model for Flood Forecasting
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Effective flood risk management requires reliable forecasts with extended lead times to enable the implementation of cost‐effective and timely measures. In this study, we present a chained hydrologic‐hydraulic modeling framework designed for effective near‐real‐time flood forecasting. The system integrates runoff predictions from a large‐scale

How Can Despeckling and Structural Features Benefit to Change Detection on Bitemporal SAR Images?
Remote Sensing, 2019 Change detection on bitemporal synthetic aperture radar (SAR) images is a key branch of SAR image interpretation. However, it is challenging due to speckle and unavoidable registration errors within bitemporal SAR images.
