A Review of Interferometric Synthetic Aperture RADAR (InSAR) Multi-Track Approaches for the Retrieval of Earth’s Surface Displacements

, 2017
Synthetic Aperture RADAR Interferometry (InSAR) provides a unique tool for the quantitative measurement of the Earth’s surface deformations induced by a variety of natural (such as volcanic eruptions, landslides and earthquakes) and anthropogenic (e.g ...

Glacier motion estimation using SAR offset-tracking procedures [PDF]

, 2002
Two image-to-image patch offset techniques for estimating feature motion between satellite synthetic aperture radar (SAR) images are discussed. Intensity tracking, based on patch intensity cross-correlation optimization, and coherence tracking, based on

Performance Analysis of Flat Surface Assumption and Residual Motion Errors on Airborne Repeat-pass InSAR

Leida xuebao, 2013
When applying to the airborne repeat-pass Interferometric Synthetic Aperture Radar (InSAR), which has long synthetic aperture and large azimuth-dependent errors, the surface assumption used to simply the time-domain algorithm model and the residual ...

Autonomous extraction of millimeter-scale deformation in InSAR time series using deep learning

Nature Communications, 2021
A deep neural network is developed to automatically extract ground deformation from Interferometric Synthetic Aperture Radar time series. Applied to data over the North Anatolian Fault, the method can detect 2 mm deformation transients and reveals a slow

Consideration on Singular-Point Generating Mechanisms by Analyzing the Effect of Phase-and-Polarization Optimization in PolInSAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
We elucidate the generation mechanisms of singular points (SPs) by investigating the relationship between the phase distortion and the polarization-state changes in polarimetric interferometric synthetic aperture radar (PolInSAR). We find that there is a

Temporal changes in rock uplift rates of folds in the foreland of the Tian Shan and the Pamir from geodetic and geologic data [PDF]

, 2017
Understanding the evolution of continental deformation zones relies on quantifying spatial and temporal changes in deformation rates of tectonic structures. Along the eastern boundary of the Pamir‐Tian Shan collision zone, we constrain secular variations
