TerraSAR-X, Germany's first national remote sensing satellite, is implemented in a public-private partnership between the German Aerospace Centre (DLR) and EADS Astrium, Infoterra GmbH. This radar satellite, launched at June 15th 2007 supplies high-quality radar data for purposes of scientific observation of the Earth for a period of at least five years. The first part of the paper describes the key features of the TerraSAR-X mission, the high-resolution X-Band Synthetic Aperture Radar which allows the operation in Spotlight, Stripmap and ScanSAR mode with various polarizations. The second part of this paper deals with the interpretation of TerraSAR-X images under dual-use aspects, especially for security and reconnaissance purposes. Examples for relevant and characteristic target categories are listed and attributes for a precise description are defined. As a measure for resolution and interpretation the public NIIRS-table (National Image Interpretation Rating Scale) is used. As an application example the characteristic scenario of a military airport including railway and route connections are extracted. Finally the applicability of the NIIRS-table is discussed in this particular case.
