Automatic Detection of Surface Deformations by DInSAR
Proceedings of the 6th International Conference on Telecommunications and Remote Sensing, 2017Due to the noise of various sources present in the interferograms and the differential interferograms, the detection of surface deformations by differential interferometry (DInSAR) is thereby a difficult and complicated task. However, the adoption of a visual inspection method for the measured results interpretation can lead to false interpretations ...

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 ...

DInSAR in displacement detection after seismic events
10th Congress of the Balkan Geophysical Society, 2019Summary Earthquakes have devastating effect on population, landscape and economy. Since it is quite challenging to predict those events of utmost importance is to obtain reliable information after they had happened. This information is essential for rescue operations and for preparation of post-event management plans.

An Underground-Mining Detection System Based on DInSAR
IEEE Transactions on Geoscience and Remote Sensing, 2013Underground mining easily causes casualties, and illegal mining is a major contributor to this issue. It is a challenge to locate and differentiate illegal mines from approved mines over a vast area. Over the past few years, our research in satellite differential radar interferometry (DInSAR) to monitor underground-mine-induced surface subsidence has ...

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.

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.

Accurate DInSAR stack coherence estimation exploiting phase statistics
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015Differential Synthetic Aperture Radar (SAR) Interferometry (DInSAR) coherence, a measurement of the similarity between two radar acquisitions, is a widely used index to quantitatively evaluate the quality of derived interferograms considering its direct relationship with Signal to Noise Ratio (SNR). When interferometrie measurements originate from both

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.

Deformation Monitoring of Volcanic Eruption Using DInSAR Method
2017The high-resolution images provided by TerraSAR-X satellite is very much useful for the displacement monitoring of earth phenomenon. In this paper, a model is developed for the deformation monitoring of Kilauea volcano in Hawaii Island region. This deformation monitoring is done with the help of differential interferometric synthetic aperture radar ...
