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.

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 ...

GLRT persistent scatterers detector

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
In this paper we investigate the problem of detecting single coherent scatterers in multidimensional (elevation-velocity) SAR imaging. We exploit both phase and amplitude information and a GLRT approach. Multipass/multiview SAR data are used and performances are assessed referring to two different models for the scatterers: deterministic and Gaussian ...

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

Optimization of PSInSAR networks with application to TomoSAR for full detection of single and double persistent scatterers

Remote Sensing Letters, 2019
In this paper, we develop an optimized network to achieve the full detection of single and double persistent scatterers (PSs) in SAR tomography (TomoSAR).

Polarimetrically-Persistent-Scatterer-Based Automatic Target Recognition

IEEE Transactions on Geoscience and Remote Sensing, 2011
Reliable automatic target recognition (ATR) systems based on inverse synthetic aperture radar (ISAR) images require a robust feature selection. An ATR system based on polarimetric ISAR images has been recently proposed that extracts bright scatterers and uses their polarimetric signatures to define classification features. Since bright scatterers could

Assessment of subsidence in Delhi NCR due to groundwater depletion using TerraSAR-X and persistent scatterers interferometry

Imaging Science Journal, 2018
Currently, high-resolution SAR data is available from different satellites. These datasets have been proved to be a strong source to monitor land subsidence.

Four-dimensional filtering of InSAR persistent scatterers elucidates subsidence induced by tunnel excavation in the Sri Lankan highlands

Journal of Applied Remote Sensing, 2019
. During construction of the Uma Oya Multipurpose Development Project, excavation of a headrace tunnel through highly tectonized metamorphic rock was slowed by repeated major water ingress events.
