%X TerraSAR-X is a high-resolution radar satellite constellation jointly developed by German space agency and EADS Astrium. It was launched in 2007. It is not affected by weather conditions and illumination, and can provide reliable SAR images with a resolution of up to 1m. It has flexible resolution, observation mode and radar interferometry ability. It has unique advantages in large-scale terrain, thematic mapping, change detection, digital terrain model, fast mapping service and so on. It can make up for the limitations of optical images in time and space.In 2012, 8 TerraSAR-X images were obtained. The coverage area is the ecological hydrological test area of artificial oasis in the middle reaches. The acquisition time (Beijing time) is: 2012-05-242012-06-042012-06-262012-07-072012-07-292012-08-092012-08-142012-08-25, and the transit time is about 19:00 Beijing time.The 8 scene data obtained are all in stripmap mode, with a nominal resolution of 3 m and a product level of MGD. Among them, the polarization mode of the six scenes of 2012-05-242012-06-04, 2012-06-26, 2012-07-07, 2012-07-29, 2012-08-09 is HH / VV, and the incident angle is small angle (22-24 °); The polarization mode of the two images on August 14, 2012 and August 25, 2012 is VV / VH, and the incident angle is large angle (39-40 °).The TerraSAR-X remote sensing data set of integrated remote sensing observation of ecological and hydrological processes in Heihe River Basin was obtained through the German Space Agency (DLR) cooperative project "estimation of eco hydrological variables using TerraSAR-X data in the Heihe River Basin, China" (No.: hyd2096)
