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 ...

Wide area persistent scatterer interferometry

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
The persistent scatterer interferometry (PSI) is a well established radar technique to monitor the Earth's displacements with millimetre accuracy. It uses men made features typically made of metal (persistent scatterers) given by chance to form interferometric phase time series spanning many years.

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

Multi beam joined estimation for persistent scatterer interferometry

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The persistent scatterer interferometry (PSI) is a powerful technique to monitor the line of sight (LOS) deformation with Millimeter accuracy in urban areas [1], [2]. Nowadays, this technique is well established for the sensors ERS and Envisat/ASAR. Nevertheless, the availability of high resolution SAR sensors enables new applications which require new

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 ...

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.

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
