Paper Abstract

Ground based Synthetic Aperture Radar Interferometry (GBInSAR) can set the right baseline according to the monitoring area, which is more freedom and convenient maneuverability and has been used on deformation monitoring of buildings, Bridges, etc. However, in the process of GBInSAR monitoring, atmospheric disturbances is a key factor affected the accuracy of the monitoring. According to the statistical characteristics in monitoring area images, the paper selected the Permanent Scatters (PS) points, established Delaunay triangulation and acquired the atmospheric correction of GBInSAR monitoring data for by linear interpolation. As the same time, the paper used the fixed point method to calculate the atmospheric disturbance. Then, the paper compared the both methods’ corrected results with high precision vertical data. The results showed that the PS method was better than the fixed point method. The PS method can better correct the atmospheric disturbances elements in the GBInSAR monitoring sequence, which provided reference value for further popularization and application of GBInSAR.
