A Shape Optimization Approach for Inferring Sources of Volcano Ground Deformation

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract One of the main goals of volcano geodesy is to improve the understanding of how an increase in pressure related to magma accumulation causes ground deformation in order to evaluate volcanic unrest. The inversion methods used for this purpose rely on a parametrization of the shape of the crustal volume in which pressure changes due to magma ...

InSAR bias and uncertainty due to the systematic and stochastic tropospheric delay [PDF]

open access: yes, 2015
We quantify the bias and uncertainty of interferometric synthetic aperture radar (InSAR) displacement time series and their derivatives, the displacement velocities, by analyzing the systematic and stochastic components of the temporal variation of the ...

Observations of Coherence Changes in C‐Band SAR Linked to Snow Thermodynamics and Wind Redistribution on First‐Year Sea Ice

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present novel observations of C‐band Synthetic Aperture Radar (SAR) coherence sensitivities and patterns for snow on first‐year sea ice (FYI) consistent with snow thermodynamics and wind redistribution. Wintertime SAR coherence and backscatter change observations of landfast FYI in Dease Strait, Nunavut, Canada are made using 12‐day repeat ...

Feature Enhancement of Interferometric Synthetic Aperture Radar Image Formation Using Sparse Bayesian Learning in Joint Sparsity Approach

open access: yesLeida xuebao, 2018
A novel sparse Bayesian learning approach with a joint sparsity model is proposed for Interferometric Synthetic Aperture Radar (InSAR) image formation to realize the feature enhancements of interferometric phase denoising and speckle reduction.

Intelligent Environmental Hazards Detection in Transmission Line Construction Area Based on Remote Sensing and GIS

open access: yesEngineering Reports, Volume 8, Issue 4, April 2026.
The test results displayed reveal that the proposed method efficiently accomplishes the remote sensing image processing of the area, yielding a differential interferogram of the image. This interferogram accurately represents the area and provides a solid foundation for calculating the environmental hazard zone within the construction area.

FrFT-Based Scene Classification of Phase-Gradient InSAR Images and Effective Baseline Dependence [PDF]

open access: yes, 2015
In the literature, scene recognition from interferometric synthetic aperture radar (InSAR) images has been mainly focused on the joint use of the backscatter intensity and the coherence between interferometric image pairs.

High‐Resolution Digital Terrain Model and Land‐Surface Parameters of São Sebastião and Ilhabela, Southeastern Brazil

open access: yesGeoscience Data Journal, Volume 13, Issue 2, April 2026.
The first openly accessible 2 m‐resolution lidar‐based DTM and an extensive set of land‐surface parameters (LSPs) for the region of São Sebastião and Ilhabela, southeastern Brazil, reveal geomorphological features previously indiscernible, including past landslide deposits, drainage captures and structural lineaments.
