摘要：

Atmospheric disturbance has a greater influence on the measurement accuracy of Ground-Based SAR, and selecting a suitable atmospheric correction method is related to the reliability and accuracy of measurement results. This paper analyzes the commonly used foundation meteorological correction model and method of synthetic aperture radar. A whole scene atmospheric correction method using PS (Permanent Scatterers) atmospheric correction network is proposed in this paper, and applied to the monitoring experiment of high-risk slope in construction. The results show that the method can effectively weaken the weather effects, improve the measurement precision, accurately detect the high-risk slope instability in the region. By comparing with the results of conventional atmospheric correction method and surveying robot, it is verified that the method proposed in this paper can be effectively used in the high risk of slope deformation monitoring, furthermore the precision of meteorological disturbance can reach submillimeter level in a complex environment monitoring. © 2016, Research and Development Office of Wuhan University.
