Adapting Stamps for Jointly Processing Distributed Scatterers and Persistent Scatterers

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
The last ten years have seen continuing progress in the field of deformation analysis based on Interferometric Synthetic Aperture Radar (InSAR) data. In particular, refined methods for processing distributed scatterers and integrated approaches that jointly use distributed scatterers (DS) and persistent scatterers (PS) have been developed.

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

Persistent Scatterer Statistics and Their Detection

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
InSAR time series analysis of deformation fields requires a set of single look complex (SLC) radar images whose pixels accurately represent the InSAR phase. In some surface cover environments, such as vegetated regions where plant growth produces echoes unrelated to the underlying surface, reliable phase estimates are difficult to identify.

Assignment of Persistent Scatterers to Buildings

IEEE Transactions on Geoscience and Remote Sensing, 2016
This paper deals with the assignment of persistent scatterers (PSs) to buildings represented by a 3-D city model. Affiliating PSs to real-world structures is highly relevant for two reasons. First, it facilitates interpretation of PS deformation estimates and can be even used to improve those estimates using advanced deformation models for complete ...

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 ...

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.
