SummaryMonitoring natural landslide hazards in a wide mountainous area has been a worldwide problem for a long time. Synthetic Aperture Radar Interferometry (InSAR) technique, which is a main profile of satellite SAR application, has been an important developmental direction of microwave remote sensing in recent years. Although the InSAR technique is still under development and there are several bottlenecks that need to be solved; however, because it has an ability to theoretically measure a very small movement of the ground for a continuous large areas, this technique can be considered as a potentially ideal tool for monitoring and forecasting occurrence of landslides. Our research will focus on monitoring Chinese landslides deforamtion using InSAR techniques.Chongqing , located in the southwest china, is the key research area because of its recent activities. PS-InSAR, CR-InSAR and Azimuth Interferometry methods will be adopted. We expected that the landslide history deformation information is obtained in order to analyze the landslidesf collapse range and predisposing factors. The Principal Investigator (PI) is funded by: 1. Geological disaster monitoring by InSAR technique over Chongqing, China (2012000200610070),2012-2013,1,200,000. 2. Nature Science Foundation of China(NSFC)(No:41072266),2012-2013,400,000.
