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.

Temporary targets for Arctic InSAR
2014 IEEE Geoscience and Remote Sensing Symposium, 2014The Arctic environment offers the biggest challenge for In-SAR; huge seasonal change, ice and snow cover for much of the year, and large variations in soil moisture. Yet the Arctic is often seen as a barometer for climate change and therefore being able to exploit technologies such as InSAR provides invaluable information not only for the communities ...

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 ...

Influence of hydrometeors on InSAR observations
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Repeat-pass synthetic aperture radar interferometry is an important tool for measuring Earth surface topography and/or surface deformations. These observations, however, are highly affected by the atmosphere. Therefore, an accurate description of atmospheric distortions is very important to improve an accuracy of interferometric measurements.

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 ...

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 ...

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 ...

Anisotropy of atmospheric delay in InSAR and its effect on InSAR atmospheric correction
Journal of Geodesy, 2018Reconstruction 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.

EZ-InSAR-3: an open-source InSAR environment in Python
In geosciences, geodesy and geotechnical engineering, Interferometric Synthetic Aperture Radar (InSAR) has demonstrated its ability to estimate, at millimetre scale, displacements of the Earth's ground surface. Although open-source SAR/InSAR software packages are robust, they are often not user-friendly, as users must have in-depth knowledge of SAR ...Alexis Hrysiewicz, Eoghan Holohan
