TerraSAR-X is a new German radar satellite that shall be launched in April 2006. The expected lifetime is 5 years. It carries a high frequency X-band SAR sensor that can be operated in different modes and polarization. The Spotlight(1.3 m), Stripmap(3.3 m) and ScanSARmodes (14.8 m) provide high resolution SAR images for detailed analysis as well as wide swath data whenever a larger coverage is ...

In this study we compared the accuracy of low-pulse airborne laser scanning (ALS) data, multi-temporal high-resolution noninterferometric TerraSAR-X radar data and a combined feature set derived from these data in the estimation of forest variables at plot level. The TerraSAR-X data set consisted of seven dual-polarized (HH/HV or VH/VV) Stripmap mode images from all seasons of the year. We were...

TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) opens a new era in spaceborne radar remote sensing [1]-[3], [9], [12]. Realized in the framework of a public-private partnership between the German Aerospace Center (DLR) and EADS Astrium GmbH, a single-pass SAR interferometer with adjustable baselines in acrossand in along-track directions was formed by adding a second (TDX), almos...

Since beginning of 2008 products of TerraSAR-X have been available for the scientific community and the great performance of this satellite system has been proven by encouraging results presented during the recent workshops and conferences. Outstanding technical features of TerraSAR-X are multiple geometric and radiometric imaging as well as the short revisiting time of 11 days. These offer the...

TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) opens a new era in space borne radar remote sensing. A single-pass SAR-interferometer with adjustable baselines in acrossand in along-track directions is formed by adding a second (TDX), almost identical spacecraft, to TerraSAR-X (TSX) and flying the two satellites in a closely controlled formation. TDX has SAR system parameters whi...

TanDEM-X is a German Public Private Partnership project between DLR and EADS Astrium for a novel satellite constellation based on TerraSAR-X with the goal to generate a global digital elevation model (DEM) according to the HRTI-3 standard, i.e. 10 m horizontal spacing and 1-2 meter vertical accuracy. TerraSAR-X is a civil German X-Band Synthetic Aperture Radar (SAR) satellite to be launched in ...

High resolution remote sensing Synthetic Aperture Radar (SAR) data from TerraSAR-X/Tandem-X satellites are used to determine and monitor the sea surface in near real time and all weather and illumination conditions. The radar backscatter of the sea surface is determined by the sea surface roughness caused by the wind field and the sea state. These meteo parameters are modelled by the newly deve...
