A Fast 2-D Phase Unwrapping Algorithm Based on Convolutional Neural Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Two-dimensional phase unwrapping (2-D PU) is the process of converting the measured phase into the real phase in interferometric signal processing. Reliable unwrapping results are critical for digital elevation model generation using interferometric ...

Calibrating interferometric synthetic aperture radar (InSAR) images with regional GPS network atmosphere models [PDF]

Geophysical Journal International, 2015
Interferometric synthetic aperture radar (InSAR) technology provides a valuable tool for obtaining Earth surface deformation and topography at high spatial resolution for crustal deformation studies. Similar to global positioning system (GPS), InSAR measurements are affected by the Earth's ionospheric and tropospheric layers as the electromagnetic ...

Ground deformation and fissure activity in Datong basin, China 2007–2010 revealed by multi-track InSAR

Geomatics, Natural Hazards & Risk, 2019
The Datong basin is one of the complex geologic environments in China. Several faults are distributed in the basin, and a number of hidden faults have been discovered within the basin. Ground fissures (GFs) and land subsidence occur in this region.

Improving Digital Mapping of Soil Organic Carbon and Total Nitrogen Through Integration of Sentinel‐1 Backscatter, InSAR Coherence, and Sentinel‐3 OLCI/SLSTR Observations

Land Degradation &Development, EarlyView.
ABSTRACT The potential of optical satellites for the spatial prediction of soil organic carbon (SOC) and total nitrogen (STN) has long been recognized. Owing to their balanced spatial–temporal resolution, multisource observational capabilities, and unprecedented availability of free data, Sentinel satellites offer unique opportunities for mapping soil ...

Bibliometric Analysis of Interferometric Synthetic Aperture Radar (InSAR) Application in Land Subsidence from 2000 to 2021

Journal of Sensors, 2022
Land subsidence is one of the serious natural disasters which can cause heavy casualties and economic losses. As a vital method, Interferometric Synthetic Aperture Radar (InSAR) can provide quick and efficient solutions for analysis. Currently, most reviews on InSAR application in land subsidence only focused on single types of land areas, such as the ...

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Transient Creep on the Yarlung Zangbo Suture in Southern Tibet Triggered by the 2015 Gorkha (Nepal) Earthquake

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large earthquakes often elevate seismicity in surrounding regions, as seen on the Xainza‐Dinggyê rift in southern Tibet after the 2015 MW 7.8 Gorkha (Nepal) earthquake. In contrast, the EW‐trending Yarlung Zangbo suture (YZS), located directly north of this event, exhibits seismic quiescence.
