Airborne DInSAR time series at X-Band

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
Differential SAR Interferometry (DInSAR) is a remote sensing technique which allows monitoring ground deformation with accuracy of the order of the transmitted wavelength by exploiting the phase difference (interferogram) of two temporally separated SAR images relevant to the same area.

DInSAR measurements of reclaimed costal land

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
The subsidence rate in a reclaimed coastal land has been estimated using JERS-1 L-band SAR two-pass differential interferometry (DInSAR). Owing to the severe temporal decorrelation induced by frequent soil loading and to the intense deformation gradient, the L-band was effective for observation of subsidence in the reclaimed land.

Dynamic deformation retrieval for DInSAR data

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
This study presents a dynamic deformation retrieval method for differential synthetic aperture radar interferometry (DInSAR) processing. Detailed nonlinear displacement parameters are modeled and estimated for capturing the developing trends of ground movement both in time and space.

Mitigation of atmospheric noise in DinSAR technique

2019 XVIII Workshop on Information Processing and Control (RPIC), 2019
Atmosphere 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.

SBAS-DInSAR time series generation on cloud computing platforms

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
This paper proposes a parallel model for the Differential Interferometry Synthetic Aperture Radar approach referred to as Small BAseline Subset (SBAS) algorithm. This new computational model has been designed to be specifically exploited within the emerging cloud computing environments.

Automatic Detection of Surface Deformations by DInSAR

Proceedings of the 6th International Conference on Telecommunications and Remote Sensing, 2017
Due 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

2014
The 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, 2019
Summary 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, 2013
Underground 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, 2018
In 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.
