Large-scale ground deformation in Iceland is dominated by extensional plate-boundary deformation, where the Mid-Atlantic Ridge crosses the island, and by uplift due to glacial isostatic adjustment from thinning and retreat of glaciers. While this deformation is mostly steady over multiple years, it is modulated by smaller-scale transient deformation ...

For interferometric SAR processing (InSAR), the quality of the interferogram is affected by many factors such as Doppler centroid difference, baseline, atmospheric effect. It can be measured by the estimation of the coherence of the data. It has been shown that the coherence image can be used to do the classification in the area such as water, soil ...

Geosynchronous InSAR and D-InSAR
2018Geosynchronous SAR has almost the same trajectory during its orbit period which makes it suitable for interferometric SAR and differential interferometric SAR (InSAR and D-InSAR) processing. But the very large orbit height, which is about 60 times larger than that in a low Earth orbit SAR, will cause lots of special issues in the repeated-track InSAR ...

Vegetation modelling for height inversion using InSAR/Pol-InSAR data.
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007The random volume over ground model has been extensively used for forest height inversion using Pol-InSAR data. Two different forest models are proposed to better represent the forest structure for height inversion using Pol-InSAR. The first one takes into account a vertically varying mean extinction coefficient and the second one considers ...

InSAR Analysis of Underground Gas Storage
IGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023Natural gas is an important source of energy used for domestic, industrial and transport purposes. Its presence is unevenly distributed in the world, and its consumption is subject to large seasonal fluctuations. In addressing this challenge, Underground Gas Storage (UGS) represents an important option to create national strategic reserves and helps ...

Comparison between InSAR and leveling
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004The Differential SAR Interferometry (DInSAR) technique has been applied to a test site located near Vauvert (France). A subsidence phenomenon has been previously observed by leveling. Precise monitoring of the phenomenon is needed in relation with deep (more than 1 km) exploitation of underground salt by solution mining, in order to constrain further ...

Multichromatic Analysis of InSAR Data
IEEE Transactions on Geoscience and Remote Sensing, 2013The multichromatic analysis (MCA) uses interferometric pairs of SAR images processed at range subbands and explores the phase trend of each pixel as a function of the dif- ferent central carrier frequencies to infer absolute optical path difference. This approach allows retrieving unambiguous height information on selected pixels, potentially solving ...

Integrating PS-InSAR and SBAS-InSAR for mining surface settlement monitoring
Journal of Mines, Metals and Fuels, 2022Based on 38 Sentinel-1A images, this paper imports GCP points generated by PS-InSAR into SBAS-InSAR, instead of manually selected GCP points, extracts surface deformation in the study area, and compares and analyzes with traditional GPS monitoring data.

InSAR Coherence-Decomposition Analysis
IEEE Geoscience and Remote Sensing Letters, 2010The 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.

Geodetic Network Design for InSAR
IEEE Transactions on Geoscience and Remote Sensing, 2015Ground deformation can be monitored with subcentimetric precision from space, using interferometric synthetic aperture radar (InSAR). This technique can sometimes be limited by a low density of naturally occurring phase-coherent radar targets. Measurement densification may be achieved through improvements in processing algorithms and new satellites ...
