Using DInSAR to Separate Surface and Subsurface Features
IEEE Transactions on Geoscience and Remote Sensing, 2013We report on an investigation into the use of differential interferometric synthetic aperture radar (SAR) (DInSAR) for the discrimination between surface and subsurface features in a soil, undertaken at the Ground-Based SAR Microwave Measurement Facility.

Exploitation of Multi-Frequency Data for Dinsar Processing
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018In this paper data acquired at different frequencies, namely X- and L-band are exploited to perform DInSAR analysis. The objective of this work is to present strategies to apply DInSAR by evaluating the required processing aspects to jointly estimate the deformation for multi-frequency time series.

Mitigation of atmospheric noise in DinSAR technique
2019 XVIII Workshop on Information Processing and Control (RPIC), 2019Atmosphere is a dominant source of error while working with the phase of Synthetic Aperture Radar (SAR) images. It can be observed as an additional phase pattern in affected interferograms. In this work we analyzed the influence of the atmosphere masked out the deformation pattern over an area near to San Juan city, Argentina.

Exploitation of Satellite A-DInSAR Time Series for Detection, Characterization and Modelling of Land Subsidence [PDF]
Geosciences (Switzerland), 2017 In the last two decades, advanced differential interferometric synthetic aperture radar (A-DInSAR) techniques have experienced significant developments, which are mainly related to (i) the progress of satellite SAR data acquired by new missions, such as ...

Penetration depth as a DInSAR observable and proxy for soil moisture
IEEE Transactions on Geoscience and Remote Sensing, 2003We use prior theory and experimental results to construct a quantitative relationship between soil moisture and the penetration depth of synthetic aperture radar (SAR) microwaves at L-, C-, and X-bands. This relationship is nonlinear and indicates that a change of 5% volumetric water content (VWC) can cause between 1 and 50 mm of change in C-band ...

Comparison and integration of GPS and DInSAR deformation time-series
2009 IEEE Aerospace conference, 2009We compare the surface deformation measurement capability of the Small BAseline Subset (SBAS) DInSAR technique and of the continuous Global Positioning System (GPS). The analysis is focused on the Los Angeles (California) test area where different deformation phenomena occur and a large amount of SAR data, acquired by the European Remote Sensing ...

Observational analysis of soil moisture effects on DInSAR signals
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013Different mechanisms for the impact of soil moisture on interferometric radar data have been proposed, but its magnitude, sign and even presence have barely been studied empirically and thus remain poorly understood. In this study the dependence of the phase and coherence magnitude on soil moisture was inferred empirically with regression techniques ...

Atmospheric Artifact Compensation in Ground-Based DInSAR Applications
IEEE Geoscience and Remote Sensing Letters, 2008In this letter, a coherence-based technique for atmospheric artifact removal in ground-based (GB) zero-baseline synthetic aperture radar (SAR) acquisitions is proposed. For this purpose, polarimetric measurements acquired using the GB-SAR sensor developed at the Universitat Politecnica de Catalunya are employed.

Observation of Expansive Clay Movement with DInSAR
2014The research summarized herein aims at answering the question of how movement caused by swelling clays can be observed with differential SAR (synthetic aperture radar) interferometry (DInSAR). The study area is located in the southwestern Denver metropolitan area, and was selected due to its location in a semi-arid climate, the existence of swelling ...
