Überwachung der Möhnestaumauer durch satellitengestützte Persistent Scatterer Interferometrie
2022Im Bereich der Infrastrukturüberwachung gewinnen Methoden der Radarfernerkundung mittels Satellitendaten an Bedeutung. Insbesondere die Technik der Persistent Scatterer Interferometrie (PSI) hat sich in diversen Studien als kostengünstige und genaue Ergänzung zu traditionellen Vermessungstechniken etabliert.

4D change detection based on persistent scatterer interferometry
2016 9th IAPR Workshop on Pattern Recogniton in Remote Sensing (PRRS), 2016We propose a novel time series analysis based on persistent scatterer interferometry (PSI) to detect spatial big changes (3D) such as construction along with their occurrence times (1D). PSI detects and analyses persistent scatterer (PS) points, which are characterized by strong and coherent signals throughout time-series SAR images and usually form ...

Nationwide ground deformation monitoring by persistent scatterer interferometry
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015The availability of long time series of interferometric data acquired all over the world from several synthetic aperture radar (SAR) satellite missions makes possible to perform a worldwide assessment of the terrain and infrastructure stability by persistent scatterer (PS) SAR interferometry techniques.

Wide area Persistent Scatterer Interferometry: Current developments, algorithms and examples
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013In recent years, Persistent Scatterer Interferometry (PSI) [1], [2] has been widely used for scientific applications and has developed into an operational and commercially rewarding remote sensing technology. Now, ESA's upcoming Sentinel-1 mission allows a continuous, repeated without gap and global mapping of the Earth's surface based on Terrain ...

Persistent Point Scatterers in multibaseline SAR interferometry
2012This paper addresses the problem of selecting Persistent Point Scatterers (PPS) in a stack of interferometric Synthetic Aperture Radar images suitable for accurate SAR parameters estimation. PPS are a subset of the well known Persistent Scatterers: besides the usual PS properties, they are characterized by an impulsive trend and a good degree of ...

Land displacement in Ordos, China, between 8 January 2007 and 19 January 2011 was mapped using L-band ALOS PALSAR data. Twenty ALOS PALSAR scenes acquired were utilised to generate both PSI and DInSAR results. Several locations in the eastern Ordos experiencing rapid land subsidence were identified including Huo Luo Wan coalmine and Qu Jia Liang ...

Persistent Scatterer Interferometry based on geodetic estimation theory
2014The Earth's surface is continuously deforming due to natural and anthropogenic processes, such as tectonics, landslides, oil and gas extraction, and groundwater level changes. Persistent Scatterer Interferometry is a technique that provides measurements of this surface motion based on satellite radar images.
