%X This data set contains SLC satellite data products of sentinel-1 in Weihe River basin without other manual processing. Sentinel-1 satellite is an earth observation satellite in the Copernicus program (Gmes) of the European Space Agency（ https://scihub.copernicus.eu/dhus/#/home ）It consists of two satellites and carries C-band synthetic aperture radar, which can provide continuous images (day, night and all kinds of weather). It is the first of five missions developed by ESA for the Copernicus program. Among them, SLC product is the first-class product after processing, which can obtain phase and amplitude information and can be used for ranging and deformation observation; Among them, the dual polarization mode VV + VH is selected; The main acquisition mode is IW. The SLC in IW mode contains three images corresponding to three bands under single polarization. 250 km long data is obtained with a spatial resolution of 5 m x 20 m (single view). Sentinel-1 satellite data is collected from January 2015 to August 2021. It is located in Gansu Province, Shaanxi Province and Ningxia Hui Autonomous Region. It needs 11 scenes, and sentinel-1 satellite data can fully cover the Weihe River Basin.
