Sea Surface Wind Field by X-band Terrasar-x and Tandem-x
In the present study, we present the newly developed Geophysical Model Function (GMF), denoted XMOD2, to retrieve the sea surface wind field from X-band TerraSAR-X/Tandem-X (TS-X/TD-X) data. In contrary to the previous XMOD1, XMOD2 is based on a nonlinear GMF, and moreover it also depicts the difference between upwind and downwind of the sea surface backscatter. By exploiting 371 collocations, ...
متن کاملSea Surface Speed from Terrasar-x Ati Data
The paper presents a methods to retrieve the speed of the sea surface from Along Track Interferometry (ATI) data beside the typical use for target speed retrieval, which is also mentioned. The describe technique provides for a data prefiltering in order to obtain the necessary accuracy because of the law speed range of the currents. Furthermore, an example of target velocity estimation is provi...
متن کاملDerivation of Sea Surface Wind Directions from TerraSAR-X Data Using the Local Gradient Method
Derivation of sea surface wind direction is a key step of sea surface wind retrieval from spaceborne Synthetic Aperture Radar (SAR) data. This technical note describes an implementation of the Local Gradient (LG) method to derive sea surface wind directions at a scale of a few kilometers from X-band spaceborne SAR TerraSAR-X (TS-X) data in wide swath mode. The 180 ̋ ambiguity in the derived sea ...
متن کاملAbsolute Ranging for Maritime Applications using TerraSAR-X and TanDEM-X Data
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...
متن کاملGeocoding of Terrasar-x Data
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 polarisation. The Spotlight-, Stripmapand ScanSARmodes provide high resolution SAR images for detailed analysis as well as wide swath data whenever a larger coverage is required. Imaging will ...
