3-d coastal water front visualization using radarsat-1 sar satellite data

Abstract

This paper presents work done to utilize RADARSAT-1 SAR data to reconstruct 3-D of coastal water front.Three algorithms of velocity bunching, Volterra and fuzzy B-spline are used to reconstruct 3-D coastal front.The velocity bunching algorithm modeled significant wave height, Volterra algorithm simulated coastal current movement while fuzzy B-spline implemented the significant wave height to reconstruct 3-D coastal front.The study shows the significant wave height varied between 0.7m to 1.3m across the front.The front is dominated by strong tidal current that ranged between 0.9 m/s to 1.5 m/s.This front occurred in water depth of 20 m.Additionally, fuzzy B-spline reconstructed 3-D front with smooth graphic feature.Indeed, fuzzy B-spline tracked the smooth and rough surface.Finally, fuzzy B-spline algorithm can keep track of uncertainty with representing spatially clustered gradient of flow points across the front.In conclusion, the fuzzy B-spline algorithm can be used for 3-D front reconstruction with integration of velocity bunching and Volterra algorithm.
