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

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

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Modern engineering systems require advanced uncertainty‐aware model updating methods that address parameter correlations beyond conventional interval analysis. This paper proposes a novel framework integrating Riemannian manifold theory with Gaussian Process Regression (GPR) for systems governed by Symmetric Positive‐Definite (SPD) matrix ...

Interferometric Synthetic Aperture Radar (SAR) Missions Employing Formation Flying [PDF]
Proceedings of the IEEE, 2010 This paper presents an overview of single-pass interferometric Synthetic Aperture Radar (SAR) missions employing two or more satellites flying in a close formation. The simultaneous reception of the scattered radar echoes from different viewing directions by multiple spatially distributed antennas enables the acquisition of unique Earth observation ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

An interferometric technique for synthetic aperture ground-penetrating radar [PDF]
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002 Many synthetic aperture radar (SAR) algorithms for ground-penetrating radar involve making measurements along a single path and using the collected data to form a two-dimensional image of the scattering object. In the calculation of these images, certain assumptions are made about the scattering objects; mainly, that the reflections are occurring ...
