Abstract

differentioal sysnthetic aperature radar interferometry (DInSAR). Fuzzy B-spline is used to accelerate and improve the accuracy of 3D map from DInSAR. DInSAR algorithm is involved two parts: 3D map simulation and interferogram simulation with DEM and satellite orbit parameters. 3D coastal geomorphology reconstruction is realized by fuzzy B-spline algorithm with the midpoint displacement method and the terrain roughness and average slope are determined by two describing parameters of the model. Furthermore, fuzzy B-spline was used to eliminate topographic phase from the interferograms. 3 RADARSAT-1 data sets of fine beam mode (F4) had been obtained between November 1999 and March 2003, and 3 coherent interferograms were generated from them. The real 3D coastal geomorphology elevation have been collected along the shoreline of Kuala Terengganu Malaysia. The study shows the DInSAR provides information about coastal geomorphology change with accuracy of ± 0.2 m. It can be concluded that the integration between DInSAR and fuzzy B-spline can provide accurate map of 3D coastal geomorphology construction from historical RADARSAT-1 SAR fine mode data.
