DInSAR%Hunshandake Sandy Land%height change monitoring%sandstorm
The DInSAR technique is used for monitoring the desert height changes to study sandstorms.Hunshandake Sandy Land, as the test area, is one of the main sources of sandstorms in Beijing.In order to study the sandstorm source and its impact, a pair of EnviSat ASAR images of Oct.11, 2005, and Oct.26, 2004, is processed on the basis of analysis of six ERS-2 and EnviSat radar images.After the image configuration, flat earth effect correction, data filtering, phase unwrapping, and geo-coding, a deformation model over Hunshandake desert is built.According to the results, the height decreased in most areas and increased in a few areas, which basically coincides with the strong sandstorm appearing in Beijing in the Spring of 2005.The results show DInSAR has an important role in monitoring of desert surface deformation.
