摘要：DInSAR techniques can be used to monitor changes in desert height due to sandstorms. Hunshandake Sandy Land was used as the test area and was a main source of sand in the vicinity of Beijing. In order to study the source of sandstorm and its impact, a pair of EnviSat ASAR images for January 20 and October 26, 2004 were processed. After the image configuration, flat earth effect correction, data filtering, phase unwrapping and geo-coding, a deformation model over Hunshandake was built. The deformation in the test area ranges from -160 to 120 cm, and the height increased in most areas and decreased in a few locations, which is generally consistent with the sandstorm appearing at Beijing during 2004.
