Practical demonstration of robust InSAR optimization for multipass InSAR

, 2016
Multipass / multibaseline SAR interferometric measurements may suffer from, for example, non-Gaussian scatterers in the context of distributed scatterers, and unmodeled interferometric phase such as unmodeled motion phase and atmospheric phase. Robust InSAR Optimization (RIO) is a framework that systematically tackles these problems.

Spatiotemporal Patterns of Subsidence and Sea Level Rise in the Samoan Islands 15 Years After the 2009 Samoa‐Tonga Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Fifteen years after the 2009 Samoa‐Tonga earthquake, rates of subsidence on the Samoan Islands remain elevated compared with pre‐earthquake levels. Coastal flooding has become a regular occurrence, increasing coastal erosion, risk of saltwater intrusion in freshwater aquifers, and threats to critical infrastructure.

InSAR phase unwrapping: a polarimetric approach

RADAR 2002, 2003
This paper addresses a polarimetric approach to improve the interferometric phase estimation based on an extension of the ESPRIT algorithm applied to different kinds of scatterers. The basics of SAR interferometry are presented. The article introduces the ESPRIT algorithm using polarimetric data with a description of the scattering model, the ESPRIT ...

Inferring 3‐D Rheology of Low‐Viscosity Zone Around Quaternary Volcanoes of NE Japan From Postseismic Deformation of the 2011 Tohoku‐Oki Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Several geological and geophysical studies suggest the small‐scale presence of low viscosity zone (i.e., LVZ) beneath the Quaternary volcanoes of northeastern Japan. Before the 2011 Mw9.0 Tohoku‐oki earthquake, scientists hypothesized that these LVZs cause localized crustal deformations around the Quaternary volcanoes. However, the deformation‐

Assessing land subsidence from anthropogenic activity in Northern Sumatra, Indonesia revealed using SAR interferometry

Journal of Degraded and Mining Lands Management
Land subsidence is a significant issue in urban areas globally, including several cities with a growing population in Northern Sumatra, Indonesia. This study employs Sentinel-1 SAR data and the Small Baseline Subset (SBAS) InSAR technique to monitor land

Breakwater settlement monitoring with InSAR data

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
This paper presents a use case of the Persistent Scatterer Interferometry (PSI) technique apply to Civil Engineering to monitor the dikes settlement on the Port of Barcelona. A geostatistical analysis of the two available datasets of PSI data have been made on a Geographic Information System to obtain a continuous deformation surface.

Characterizing Shallow Aseismic Deformation Along the Dead Sea Pull‐Apart Basin Using Geodetic Observations

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract We use creepmeter (CM), Global Navigation Satellite System (GNSS), Interferometric Synthetic Aperture Radar (InSAR) and airborne Light Detection and Ranging (LiDAR) observations to characterize transient aseismic deformation along the central Dead Sea pull‐apart basin, which is located at the southern part of the sinistral Dead Sea Fault (DSF).
