Application of Deformation Monitoring in Pumped Storage Power Station Based on Ground-based Radar Interferometry

High precision deformation monitoring is required to provide security assurance during construction of hydropower stations. As a new deformation monitoring method in recent years, ground-based radar interferometry meets the requirements of high spatio-temporal resolution and high precision deformation monitoring. In this paper, the data processing method of ground-based radar interferometry is discussed, and take the slope of Chongqing Panlong Pumped Storage Power Station is taken as an example to verify effectiveness of the ground based radar interferometry in deformation monitoring of hydropower stations.
