TerraSAR-X and its almost identical twin satellite TanDEM-X have provided high resolution radar images and Digital Elevation Models with unprecedented accuracy for years. Between December 2010 and early 2015, radar data of all land surfaces has been acquired and as of September 2016 the final global DEM dataset has been available. Furthermore a science phase generating radar products for scientifi...Show More
TSX, an advanced synthetic aperture radar satellite, launched on June 15th 2007 and the almost identically rebuild TDX satellite, launched on June 21th 2010 serve two challenging radar missions. First: The TerraSAR-X mission, providing high quality SAR data for scientific and commercial purposes, covering a large variation of SAR modes from a high resolution staring spotlight mode with 1 m resolut...Show More
TerraSAR-X is a new German radar satellite that was launched in June 15, 2007. It carries a high frequency X-band SAR sensor that can be operated in three different modes and various polarizations. The Spotlight-, Stripmap- and ScanSAR-modes provide high resolution images for detailed analysis as well as wide swath data whenever a larger coverage is required. These high geometric and radiometric r...Show More
This paper describes the TerraSAR-X mission concept within the context of a public-private partnership (PPP) agreement between the German Aerospace Center (DLR) and the industry. It briefly describes the PPP concept as well as the overall project organization. This paper then gives an overview of the satellite design and the corresponding ground segment, as well as the main mission parameters. Aft...Show More
TerraSAR-X, the first national German remote-sensing satellite, was launched on June 15, 2007. It carries an X-band high-resolution synthetic aperture radar (SAR) instrument featuring imaging modes like StripMap, ScanSAR, and, particularly, SpotLight in a variety of different polarization modes. Primary mission goal is the provision of both science and commercial users with a variety of products f...Show More
TerraSAR-X is Germany's first national remote sensing satellite being implemented in a public-private partnership between the German Aerospace Centre (DLR) and EATS Astrium GmbH. TerraSAR-X was launched on June 15, 2007 and will supply high-quality radar data for purposes of scientific observation of the Earth for a period of at least five years. At the same time, it is designed to satisfy the ste...Show More

Since the beginning of 1994 the Institut fu/spl uml/r Hochfrequenztechnik of the German Aerospace Center (DLR) has been operating an experimental airborne SAR E-SAR with a P-band radar front-end. The microstrip patch array antenna allows a signal bandwidth of slightly more than 10% of the 450 MHz carrier frequency. The radar is polarimetric on a pulse-to-pulse basis.Show More
Two new motion compensation methods for airborne SAR are presented. Both methods are based on the evaluation of acceleration data measured by an Attitude and Heading Reference System (AHRS). The motion compensation algorithms were developed for the Experimental SAR System (E-SAR) of DLR which operates in L/C/X-Band. It is installed in a small Dornier Do-228 turboprop aircraft. Due to atmospheric t...Show More
