Vertical Resolution Enhancement by Applying Polarimetric Spectral Analysis Techniques to Multibaseline InSAR Data [PDF]
Polarimetric spectral analysis techniques have been recently introduced for processing multibaseline interferometric synthetic aperture radar data that are affected by the speckle phenomenon.

SEMANTIC INTERPRETATION OF INSAR ESTIMATES USING OPTICAL IMAGES WITH APPLICATION TO URBAN INFRASTRUCTURE MONITORING [PDF]
Synthetic aperture radar interferometry (InSAR) has been an established method for long term large area monitoring. Since the launch of meter-resolution spaceborne SAR sensors, the InSAR community has shown that even individual buildings can be monitored

MSWD: A Hybrid Machine‐Learning Framework for Slant Wet Delay Modeling
Abstract Space geodetic techniques such as Global Navigation Satellite Systems (GNSS) and Very Long Baseline Interferometry (VLBI) are limited by direction‐dependent tropospheric delays, with slant wet delay (SWD) being the most variable component and a major error source.

One of the effects of an earthquake is the creation of displacement on the land surface. It’s important to determine displacement due to natural disasters such as earthquakes. So, it’s essential to identify height changes occurring on Earth due to these movements.

Interseismic Creep Along the Enriquillo–Plantain Garden Fault, Haiti, Estimated From InSAR
Abstract The Enriquillo–Plantain Garden fault zone (EPGFZ) is a major left‐lateral strike‐slip fault in southern Haiti hosting several recent destructive earthquakes, including the 2021 MW 7.1 Nippes event with primary thrust‐slip. To investigate how strain is accommodated in the vicinity of the 2021 event, we analyzed Sentinel‐1 interferometric ...

Modeling Orbital Error in InSAR Interferogram Using Frequency and Spatial Domain Based Methods
Synthetic Aperture Radar Interferometry (SAR, InSAR) is increasingly being used for deformation monitoring. Uncertainty in satellite state vectors is considered to be one of the main sources of errors in applications such as this.

Detecting peat‐like behaviour areas using European Ground Motion Service data
This study presents a scalable approach for detecting peat‐like behaviour areas (PBAs) using open‐access InSAR time series from the European Ground Motion Service. The method integrates unsupervised principal component analysis (PCA) and k‐means clustering to complement optical mapping and reveal peat‐like dynamics, supporting improved peatland ...

Abstract Drained and cultivated grasslands on peat soils behave as a significant source of greenhouse gasses by oxidation. However, the lack of empirical estimates of carbon losses from peatlands with adequate spatial and temporal resolution has forced researchers to rely on process‐based model approximations to make quantitative, regional‐ or national‐
