An Approach to Persistent Scatterer Interferometry [PDF]
Remote Sensing, 2014 This paper describes a new approach to Persistent Scatterer Interferometry (PSI) data processing and analysis, which is implemented in the PSI chain of the Geomatics (PSIG) Division of CTTC. This approach includes three main processing blocks. In the first one, a set of correctly unwrapped and temporally ordered phases are derived, which are computed ...

Detecting changes in persistent scatterers [PDF]
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013 In PSI (Persistent Scatterer Interferometry) the PSs are implicitly assumed to have a stable phase throughout a stack of images so that all images can be used for estimation. However, PSs can fade due to changes in acquisition geometry where the elevation or azimuth response of the PS for different baselines or zero Doppler frequencies is imprinted on ...

Terrain objects movement detection using SAR interferometry [PDF]
Компьютерные исследования и моделирование, 2015 To determine movements of infrastructure objects on Earth surface, SAR interferometry is used. The method is based on obtaining a series of detailed satellite images of the same Earth surface area at different times.

Matching of Persistent Scatterers to buildings [PDF]
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012 Persistent Scatterer Interferometry (PSI) aims at estimating the topography and deformation for a set of sufficiently stable radar targets, referred to as Persistent Scatterers (PS). Thereby, a stack of SAR images is exploited to distinguish between signal of interest and disturbances caused by, for instance, changes of the atmospheric conditions over ...

URBAN MONITORING BASED ON SENTINEL-1 DATA USING PERMANENT SCATTERER INTERFEROMETRY AND SAR TOMOGRAPHY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 A lot of research and development has been devoted to the exploitation of satellite SAR images for deformation measurement and monitoring purposes since Differential Interferometric Synthetic Apertura Radar (InSAR) was first described in 1989.

Performance Improvement for SAR Tomography Based on Local Plane Model
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Multilook approaches have been applied in synthetic aperture radar (SAR) tomography (TomoSAR), for improving the density and regularity of persistent scatterers reconstructed from multipass SAR images in both rural and urban regions. Multilook operations
