Research on the Application of InSAR Technology for the Recognition of the Potential Danger of Suspected Geological Hazards
摘要
SAR images can effectively identify ground deformation, detect deformation trends, and have an incomparable advantage in surface deformation analysis, which can be used for large-scale and manpower difficult to reach areas of disaster hidden danger identification and monitoring. This paper discussed the method of SAR image processing, SAR image needs to be pre-processed such as co-registration, interferometric and filtering, phase unwrapping, geocoding, orbital refining and removal of atmospheric effects, then the InSAR image Stacking technology, SBAS technology can be better to achieve the surface deformation identification and trend analysis.
