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 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 کاملTerraSAR-X Dual Receive Antenna Mode - Channel Reconstruction and Impact on the GMTI Performance
Synthetic aperture radar with multiple channels separated in along-track direction allows for GMTI such as detection of road traffic [1]. With TerraSAR-X two receive channels separated in along-track direction can either be realized through switching between the fore and aft antenna halves from pulse to pulse, or with the dual receive antenna (DRA) mode [2]. While the switching in the single ch...
متن کاملGeometric Error Budget Analysis for TerraSAR-X
The impact of potential error sources on geocoded products has been investigated with respect to the high resolution capabilities of the TerraSAR-X sensor. Datum shift parameters, maps, digital terrain and surface models have been identified as external error sources. The accuracy of the geocoded products depends heavily on the quality and availability of this information, which underlies regio...
متن کاملThe TerraSAR-X Mission
The German national SAR-satellite system TerraSAR-X is based on a public-private-partnership agreement between the German Aerospace center DLR and EADS Astrium GmbH. It is the continuation of the scientifically and technologically successful radar missions X-SAR (1994) and SRTM (2000) and is designed for scientific and commercial applications. The TerraSAR-X features an advanced high-resolution...
