Tops Differential Sar Interferometry with Terrasar-x
In this paper we investigate the possibility to exploit TOPS data to measure ground displacement movements by means of Differential SAR Interferometry (DInSAR). Several critical points (i.e. coregistration) have to be faced during the data processing since, due to the TOPS signal characteristics, the interferometric chain is very sensitive to small implementation errors. The obtained results wi...
متن کاملFirst Terrasar-x Interferometry Evaluation
The German radar satellite TerraSAR-X was launched in June 2007 [1] and is currently ending its commissioning phase. We anticipate quite different interferometric application scenarios compared to ERS1/2 and ASAR due to the X-band frequency, the short orbital repeat cycles of 11 days, the high range resolution and the spotlight mode of this sensor. During the commissioning phase we have schedul...
متن کاملTerraSAR-X TOPS, ScanSAR and WideScanSAR interferometric processing
The German TerraSAR-X and TanDEM-X satellites are able to acquire images operationally in ScanSAR and WideScanSAR modes and experimentally in TOPS mode. This paper gives an overview of the interferometric processing steps of burst-mode acquisitions, emphasizing the importance of the co-registration stage. A coregistration approach based on incoherent cross-correlation is presented. Interferomet...
متن کاملFirst TOPSAR image and interferometry results with TerraSAR-X
TOPSAR is a recently proposed SAR mode for wide swath acquisition, which is foreseen to be used by the ESA Sentinel-1 SAR sensor in its main interferometric wide swath mode. The Microwaves and Radar Institute of the German Aerospace Center is validating TOPSAR mode in space with TerraSAR-X data within the framework of an ESA commissioned project. Several TOPSAR images have been successfully com...
متن کاملTerrasar-x High Resolution Spotlight Persistent Scatterer Interferometry
The new class of meter-resolution spaceborne SAR systems (TerraSAR-X and COSMO-Skymed) offers a tremendous improvement in interferometric monitoring of urban areas and man-made infrastructure. The high resolution fits well to the inherent scale of buildings (floor height, distance of windows, etc.). In particular, Persistent Scatterer Interferometry (PSI) benefits substantially from this new da...
