Landslide disaster has happened frequently in our country. Monitoring and early warning are the main means to effectively reduce the harm of landslide disaster. Different from the traditional method of monitoring, differential interferometry synthetic aperture radar (D-InSAR) measuring technique has the advantage of detecting and penetrating earth surface in all weather conditions and in all time, obtaining continuous and large-area deformation information. Taking the Jinpingzi Landslide of Jinshajiang valley as the research object. The monitoring technique of three orbits difference, the basic method of D-InSAR, is used to obtain surface deformation value. Research results show that the deformation value of Landslide boundaries is larger than the surrounding area, and the D-InSAR technology is a feasible approach for monitoring landslide.
