between the two images, which could theoretically be exploited for target velocity retrievals. However, the feasibility of ocean current measurements with SRTM has been questionable, since the time lag was much shorter than the theoretical optimum (about 3 ms at X-band) and the signal-to-noise ratio over water was quite low. Nevertheless, some X-band InSAR(More)
TerraSAR-X offers different possibilities for Along-track Interferometry (ATI) SAR data acquisition. This enables to demonstrate several new SAR applications related to the detection and measurement of ground moving objects from space. SAR Along-track interferometry has gained growing attention in recent years for large-scale and weather and daylight(More)
– We present one of the first studies in which inter-ferometric synthetic aperture radar (InSAR) data from the Shuttle Radar Topography Mission (SRTM) are analyzed with regard to the detectability of ocean surface current variations. The InSAR system of SRTM was designed for high-resolution topo-graphic mapping, using two SAR antennas on a Space Shuttle(More)
