Slope Sliding Direction Estimate Based on Ground-based D-InSAR

Landslide is a common natural geological disaster, and the development process of landslide is so complicated, then makes the prevention and control of landslide very difficult. In the process of landslide monitoring and control, the estimation of slope sliding direction is very important. Based on the monitoring data of D-InSAR (Differential Intereferometric Synthetic Aperture Radar), combined with the geometric relationship between the monitoring target and radar, as well as the objective laws observed in the natural deformation process of the slope, a method to estimate the sliding direction of the slope is proposed in this paper. This paper uses the monitoring data of two slopes as an example and verifies the feasibility and effectiveness of the method in the face of the point target and the whole slope through comparison with the monitoring data of GPS, the comparison results show good consistency.
