Research on multi-source data integration and the extraction of three-dimensional displacement field based on GBSAR

Abstract

Only the displacement along the radar line of sight can be got in Ground Based Synthetic Aperture Radar (GBSAR). In order to extract high-precision three-dimensional displacement field of research area, in this article, we research deeply the method which integrates both three-dimensional laser scanning and GBSAR techniques. It is proved that high precision three-dimensional displacement field information can be extracted with this method through analyzing case and assessing the accuracy of three-dimensional displacement field. The method has a good practical value.
