Ship Detection in Terrasar-x High-resolution Spotlight Dual-polarisation Imagery
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...
متن کاملTerrasar-x High Resolution Spotlight Persistent Scatterer Interferometry
The new class of meter-resolution spaceborne SAR systems (TerraSAR-X and COSMO-Skymed) offers a tremendous improvement in interferometric monitoring of urban areas and man-made infrastructure. The high resolution fits well to the inherent scale of buildings (floor height, distance of windows, etc.). In particular, Persistent Scatterer Interferometry (PSI) benefits substantially from this new da...
متن کاملGeometric Validation of Terrasar-x High-resolution Products
Switzerland's diversity of flat, rolling and Alpine terrain makes it ideal territory for geometric validation studies. We describe here two parallel investigations of TerraSAR-X (TSX) high-resolution data: geometric validation and estimation of the tropospheric path delay using measurements of corner reflectors (CRs) placed at different altitudes but nearly identical ranges. Geometric validatio...

متن کاملDSMs GENERATION FROM TERRASAR-X HIGH RESOLUTION SPOTLIGHT IMAGERY: EVALUATION OF RADARGRAMMETRIC APPROACHES IMPLEMENTED IN THE SCIENTIFIC SOFTWARE SISAR
One relevant application of SAR remote sensing is the generation of Digital Surface Models (DSMs) of the Earth's surface, thanks to the SAR independence from logistic constraints on the ground, illumination and weather conditions. Starting from SAR imagery two different approaches can be used to generate DSMs: the well known interferometric and the promising radargrammetric one. The goal of thi...
