Multitemporal analysis of land subsidence induced by open-pit mining activity using improved combined scatterer interferometry with deep learning algorithm optimization [PDF]
Scientific ReportsMine operational safety is an important aspect of maintaining the operational continuity of a mining area. In this study, we used the InSAR time series to analyze land surface changes using the ICOPS (improved combined scatterers with optimized point ...

Land subsidence monitoring based on PS-InSAR Persistent Scatterers identification with spectral analysis method [PDF]
Proceedings of the International Association of Hydrological Sciences, 2020 Layover occurs as a consequence of the slant range scale distortion in Synthetic Aperture Radar (SAR) data and it is commonly observed in the images acquired over urban areas. There may be two or more Persistent Scatterers (PSs) in one pixel.

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.

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 ...

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.

Scattered striated persistent nephrogram in sepsis [PDF]
Nephrology Dialysis Transplantation, 2011 Persistent nephrogram, the hallmark of radiocontrast-induced kidney failure, is usually homogenous throughout the kidney and is considered as a generalized shutoff of glomerular filtration, the consequence of altered glomerular hemodynamics, affecting most glomeruli.

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
