Abstract

Germany has successfully launched a public-private partnership satellite mission, called TerraSAR-X, which uses X-band synthetic aperture radar (SAR) to provide high-quality topographic information for commercial and scientific applications. The advanced high-resolution X-band SAR is designed for high resolution imaging and topographic mapping of land scenes, permitting current measurements in coastal waters and rivers at sub-kilometer resolution. The latest radar technology makes imaging possible by interferometric synthetic aperture radar (InSAR), which offers a high spatial resolution and the flexibility to acquire images from air or a space-borne platform. The measuring accuracy of space borne along-track interferometry (ATI) systems can be improved with respect to TerraSAR-X by an optimization of the along track antenna distance or a substantial reduction of the instrument noise level. TerraSAR-X is a pure ATI system with no cross-track antenna separation which facilitates the absolute calibration of measured currents.
