Anisotropy of atmospheric delay in InSAR and its effect on InSAR atmospheric correction

Journal of Geodesy, 2018
Reconstruction of interferometric synthetic aperture radar (InSAR) atmospheric delay maps is important for the correction of tropospheric artifacts in differential InSAR (D-InSAR) and for the improvement in persistent scatterer (PS) target identification in PS-InSAR.

Formation Flying for Distributed InSAR

AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 2006
We consider two spacecraft flying in formation to create interferometric synthetic aperture radar (InSAR). Several candidate orbits for such in InSar formation have been previously determined based on radar performance and Keplerian orbital dynamics. However, with out active control, disturbance-induced drift can degrade radar performance and (in the ...

Improved DEM Reconstruction Method Based on Multibaseline InSAR

IEEE Geoscience and Remote Sensing Letters, 2022
Digital elevation models (DEMs) are vital in the geosciences and many other fields. Interferometric synthetic aperture radar (InSAR), an advanced earth observation technology, has shown its potential in DEM reconstruction. Multi baseline InSAR (MB-InSAR)

Multi-scale feature extraction approaches for classification of insar and phase gradient insar images

2016 IEEE International Conference on Image Processing (ICIP), 2016
This paper investigates different multi-scale approaches in terms of feature extraction for classification of interfero-metric SAR (InSAR) and previously defined phase gradient InSAR (PGInSAR) images. For this purpose, the scale-space image representation approach is implemented together with the two partial derivative based structure matrices, namely ...

Forest Modeling For Height Inversion Using Single-Baseline InSAR/Pol-InSAR Data

IEEE Transactions on Geoscience and Remote Sensing, 2010
The Random Volume over Ground (RVoG) model has been extensively applied to polarimetric synthetic aperture radar interferometry (Pol-InSAR) data for forest height inversion. The model assumes forest as a homogeneous volume of randomly oriented particles characterized by a constant extinction but does not take into account the forest vertical ...

InSAR Monitoring of Landslides in Canada

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
In this study we used differential and CTM InSAR techniques to monitor landslide slides at different geological sites in Canada. Our results show that InSAR measurements are providing new information on the deformation behaviour of complex landslide processes.

InSAR for Reservoir Geomechanical Analysis

Proceedings, 2015
Reservoir monitoring improves our understanding of reservoir behaviour and helps achieve more effective reservoir management and prediction of future performance with obvious economic benefits. It relies on an integrated approach involving both data collection and modelling. Interferometric Synthetic Aperture Radar (InSAR) is a satellite remote sensing

InSAR Coherence-Decomposition Analysis

IEEE Geoscience and Remote Sensing Letters, 2010
The phase coherence in synthetic aperture radar interferometry is often used in classification algorithms to detect possible temporal changes of the imaged terrain. However, in mountain areas, the interferometric coherence is also sensitive to the slight variations of the acquisition geometry.

InSAR Imaging of Aleutian Volcanoes

2014
In this chapter we discuss our InSAR observations of Aleutian volcanoes that have been active during historical time, starting with Kiska Volcano in the west and ending with Mount Wrangell in the east. The start of historical time in Alaska is poorly defined and varies considerably with location.
