摘要
应用GPS-InSAR集成技术监测地表形变是目前地学界研究的热点问题。介绍了利用GPS对InSAR进行大气误差和轨道误差改正的方法,探讨了GPS与InSAR数据融合的方案,并通过一个实例证明:应用GPS-InSAR集成技术可以达到毫米级监测精度,其具有十分广阔的应用前景。
The powerful tool of GPS-InSAR integration is drawing more and more attention in deformation monitoring. This paper introduces firstly method of atmospheric corrections and orbit errors to InSAR images using GPS datum. Then, the scheme of GPS-InSAR data integrating is expounded, finally. The results indicate that accuracy of deformation monitoring is about the order of lmm by an example, and its broad prospects is presented.
