摘要

本文提出了一种利用差分合成孔径干涉法(DInSAR)进行三维海岸变形模拟的新方法。在此过程中，对RADARSAT-1 SAR精细模态数据(F1)进行了三次重复传递，实现了常规InSAR程序。此外，采用相位展开技术实现了DInSAR方法。因此，采用DInSAR来消除干涉图中的相位去相关影响。研究表明，DInSAR具有精确的性能，均方根误差为0:02±0:21 m，置信区间为90%。总之，DInSAR技术可以产生精确的三维海岸地貌重建。

Three-dimensional coastal geomorphology deformation modelling using differential synthetic aperture interferometry

This work presents a new approach for three-dimensional (3D) coastal deformation simulation using differential synthetic aperture interferometry (DInSAR). In doing so, conventional InSAR procedures are implemented to three repeat passes of RADARSAT-1 SAR fine mode data (F1). Further, the DInSAR method is implemented with the phase unwrapping technique. Consequently, DInSAR is used to eliminate the phase decorrelation impact from the interferograms. The study shows the accurate performance of DInSAR with a root mean square error of 0:02±0:21 m and 90% confidence intervals. In conclusion, the DInSAR technique produces an accurate 3D coastal geomorphology reconstruction.
