Abstract Monitoring water level changes is necessary to manage, conserve and restore natural, anthropogenic lake systems. However, the in‐situ monitoring of systems unfeasible due limitations costs access. Furthermore, current remote sensing methods are restricted large lakes low spatial resolutions. We develop a novel approach using subsequential pixel‐wise observations Sentinel‐1B sensor base...

Persistent scatterer interferometry (PSI) has been proved to be an advanced Interferometric Synthetic Aperture Radar (InSAR) technique used measure and monitor terrain deformation. Two of the critical problems with InSAR have effect refractive atmosphere decorrelation on interferometric phases due long spatial-temporal baseline. The low density persistent scatterers (PS) in non-urban areas affe...

Abstract. Radar interferometry has progressed very much in the last two decades. It is now a powerful remote sensing techniques to monitor ground motion. The technique undergone an important development terms of processing and data analysis algorithms. This been accompanied by increase Synthetic Aperture (SAR) acquisition capability spaceborne sensors. A step forward was launch Copernicus Senti...
