Abstract: Deformation monitoring for large-scale hydropower projects has always been a hot issue in the field of deformation monitoring. According to the principle of ground-based synthetic aperture radar measurement and the characteristics of IBIS system, we expounded the advantages of the GBInSAR(Ground-Based Interferometric Synthetic Aperture Radar) technology in dam deformation monitoring compared with traditional monitoring methods. We also analyzed the influence of atmospheric disturbance effect on the observation, and proposed technical method InSAR(Interferometric Synthetic Aperture Radar) to remove the atmospheric errors based on experimental data. Engineering practice suggests that IBIS-L deformation monitoring system has prospect of wide application in dam deformation monitoring.

Key words: deformation monitoring, GBInSAR, atmospheric disturbance effect
