Fully Integrated Temporary Persistent Scatterer Interferometry

IEEE Transactions on Geoscience and Remote Sensing, 2022
The persistent scatterer interferometry (PSI) is a powerful remote sensing technique to monitor displacements of the Earth’s surface. It is based on identifying and analyzing phase-stable scatterers undergoing marginal decorrelation over time. Most PSI approaches constrain the analysis to scatterers which are coherent over the whole considered time ...

Dynamic persistent scatterers interferometry

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
This paper presents the concept of Dynamic Persistent Scatterers Interferometry (PSI) processing, which enables the sequential estimation of parameters. The method is based on the Integer Least Squares (ILSQ) PSI concept and makes use of the estimation vector and corresponding variance-covariance matrix of the initial estimation epoch. In addition, the

Monitoring residual mining subsidence of Nord/Pas-de-Calais coal basin from differential and Persistent Scatterer Interferometry (Northern France)

Journal of Applied Geophysics, 2009
International audienceBoth differential SAR Interferometry (DInSAR) and Persistent Scatterer Interferometry (PSI) are used to estimate surface displacement of the Nord/Pas-de-Calais coal basin during a 15-year period (1992–2007) after the end of 270 ...

High surface displacement monitoring with persistent scatterer interferometry

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
PS Interferometry overcomes the temporal and geometrical decorrelation limitations through selection of so-called Persistent Scatterers (PS) with coherent scattering behavior over time using a large stack of interferometric SAR image. In Stanford Method for Persistent Scatterers, StaMPS, the deformation can be extracted even in areas lacking the corner

The Thermal Expansion Component of Persistent Scatterer Interferometry Observations

IEEE Geoscience and Remote Sensing Letters, 2011
This letter focuses on the thermal expansion component of persistent scatterer (PS) interferometry (PSI), which is a result of temperature differences in the imaged area between synthetic aperture radar (SAR) acquisitions. This letter is based on very high resolution X-band StripMap SAR data captured by the TerraSAR-X spaceborne sensor.

Landslide HotSpot Mapping by means of Persistent Scatterer Interferometry

Environmental Earth Sciences, 2012
Landslide detection and mapping represent fundamental requirements for every hazard and risk evaluation and consequent improvement of the management strategies for such natural hazards. Optical and radar remote sensing can be used to observe landslide-induced ground deformation, ranging from regional to local scales.

Improvement of Persistent-Scatterer Interferometry Performance by Means of a Polarimetric Optimization

IEEE Geoscience and Remote Sensing Letters, 2012
This letter is aimed at presenting results confirming the contribution of polarimetry to improve the performance of persistent-scatterer interferometry. The improvement is provided by the identification of more pixels with good phase quality, under criteria commonly employed in this context, after a search in the available polarimetric space.

Subsidence monitoring using polarimetric persistent scatterers interferometry

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
In this work we review the PSI polarimetric optimization method firstly introduced in [1] and apply it to a larger stack of images, in order to confirm its suitability for the obtainment of accurate deformation maps. The approach achieves a higher density of points with valid deformation information compared to single-pol data, thus confirming the ...

Urban Applications of Persistent Scatterer Interferometry

2010
This chapter reviews the urban applications of Persistent Scatterer Interferometry (PSI), the most advanced type of differential interferometric Synthetic Aperture Radar techniques (DInSAR) based on data acquired by spaceborne SAR sensors. The standard DInSAR techniques exploit the information contained in the radar phase of at least two complex SAR ...
