A CNN-Based Coherence-Driven Approach for InSAR Phase Unwrapping

open access: yesIEEE Geoscience and Remote Sensing Letters, 2022
Phase unwrapping (PU) is among the most critical tasks in synthetic aperture radar (SAR) interferometry (InSAR). Due to the presence of noise, the interferogram usually presents phase inconsistencies, also called residues, which imply a nonunivocal ...

An Onboard Calibration Technique for Synthetic Aperture Radar Interferometry Using Multisource Data

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The synthetic aperture radar interferometry (InSAR) is a powerful tool for retrieving the Earth’s geophysical parameters, such as terrain height, displacement and soil moisture.

Holistic Retrieval of Absolute Coseismic Displacement Fields From Single Interferograms via Physics‐Aware GANs

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...

PUformer: A Transformer-Based Network Architecture Design for InSAR Phase Unwrapping

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Phase unwrapping (PU) is a critical step in synthetic aperture radar interferometry (InSAR) applications. Traditional model-based PU methods rely on the empirical phase continuity assumption and thus struggle in the presence of strong noise or abrupt ...

Grid Resilience Enhancement Under Extreme Heat Wave Events

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper develops a probabilistic simulation framework to enhance grid resilience against low‐frequency high‐impact heat‐wave events by integrating residential photovoltaic (PV) generation and battery energy storage systems (BESS). A novel line‐failure probability matrix identifies thermally stressed branches and guides contingency analysis.

Minimum Cost Flow phase unwrapping supported by multibaseline unwrapped gradient [PDF]

open access: yes, 2010
The objective of the TanDEM-X Mission is the generation of a global high resolution Digital Elevation Model (DEM). To carry out this goal, two interferograms with different baselines will be acquired.

Breaking barriers: Sunlight‐activated self‐healing polymers with unprecedented photoaging resistance

open access: yesSusMat, Volume 4, Issue 6, December 2024.
Photochemical self‐healing of polymers is decoupled from the accompanying photoaging effect by introducing carbazolyl‐based dithiocarbamate bonds. The resulting crosslinked polyurethanes exhibit photoaging resistance significantly higher than the control containing commercial stabilizer, and excellent sunlight‐driven self‐healability toward surface and
