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...

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...

The SAR geolocation accuracy using TerraSAR and TanDEM-X data has been demonstrated to be into centimeter level with no need of any reference frame. This paper is intended to show potential applications over maritime scenarios based on precise absolute measurements. Two specific applications are discussed and analyzed. The first one is to measure ships 2D velocity using TanDEM-X products. The s...

For several years the technique of radargrammetry with high resolution Synthetic Aperture Radar (SAR) data has been used in scientific and commercial environment for Digital Elevation Modelling (DEM). Compared to repeat pass interferometry, radargrammetry is a robust DEM generation technique for almost all areas on the globe due to phase independent matching algorithms. Particularly in areas wi...

Rising interest in traffic monitoring applications motivate the analysis of TerraSAR-X data for traffic monitoring applications. In order to sidestep the limitations of the TerraSAR-X sensor, this paper examines a new approach to improve detection using a priori information. Using Monte-Carlo Simulation the possibility of improving detection with ATI is demonstrated.

State-of-the-art high resolution active remote sensing imaging radar, TerraSAR-X, is having all-weather and all-time data acquisition capability. It is a promising tool for mapping snow and glaciers in mountainous region. The current study has been done using dual polarization (HH/VV) Synthetic Aperture Radar (SAR) data of TerraSAR-X (TSX), to estimate the snow physical properties (snow cover, ...
