This paper presents a semi-automated approach to detecting coastal shoreline change with high spatialand temporal-resolution using X-band synthetic aperture radar (SAR) data. The method was applied at the Sand Motor, a “mega-scale” beach nourishment project in the Netherlands. Natural processes, like waves, wind, and tides, gradually distribute the highly concentrated sand to adjacent beaches. ...

This paper gives an overview of capabilities of TerraSAR-X and provides some first application results. The TerraSAR-X mission is based on a public-private-partnership agreement between the German Aerospace Centre DLR and EADS Astrium GmbH. It is the continuation of the scientifically and technologically successful radar missions X-SAR (1994) and SRTM (2000) and is designed for scientific and c...

For the TerraSAR-X mission two new modes have been implemented and are operational since autumn 2013. One is a high azimuth resolution Staring Spotlight mode and the other is a wide ScanSAR mode with doubled ground range coverage compared to the nominal TerraSAR-X ScanSAR. This paper gives an overview about SAR performance analyses conducted during the mode design and implementation phases and ...

TerraSAR-X is a new German radar satellite that shall be launched in mid 2006. The expected lifetime is 5 years. It carries a high frequency X-band Synthetic Aperture Radar (SAR) sensor that can be operated in different modes and polarisation. The Spotlight-, Stripmapand ScanSAR-modes provide high resolution SAR images for detailed analysis as well as wide swath data whenever a larger coverage ...

The TerraSAR-X SAR system provides high spatial resolution and geometric accuracy imagery which supports well the mapping of the 3-D structure of the city and its motions (4-D). In this work, we have evaluated potential of the very high resolution (VHR) satellite observations for monitoring and detecting ground deformation due to largescale civil infrastructure constructions. Two case studies w...

This paper addresses ship detection in TerraSAR-X single-look high-resolution spotlight data by using a global thresholding approach, which is based on statistical analysis of the test data. The corresponding thresholds were determined separately from the exponential and chi-squared distributions for TerraSAR-X single-polarisation (HH or VV) and dual-polarisation (HH and VV) data. From the resu...

The potential of TerraSAR-X data for deformation measurements benefits from high spatial and temporal resolution and even allow detecting higher deformation gradients compared to other sensors. However, decorrelation noise from vegetation and atmospheric effects are of greater importance because of the shorter wavelength. The extent of a TerraSAR-X scene is small compared to common scale atmosp...

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 ...

This paper presents a new method for unsupervised urban area extraction from SAR imagery. The image segmentation method combines variogram texture feature extraction with OTSU threshold segmentation method, to obtain the result as good as traditional classical algorithm and have much higher computational efficiency. TerraSAR-X image is used to validate the proposed method, and experimental resu...
