Abstract
This study presents work utilizing TOPSAR polarized data to generate three-dimensional (3D). The Fuzzy arithmetic algorithm was used to construct ocean bathymetry from polarized TOPSAR data. Estimates of sea surface current were computed by using Volterra and Fuzzy B-spline models. The continuity equation was used to estimate the water depth based on current pattern information. A Fuzzy B-Spline model which construct a global topological structure between the data points were used to support an approximation of real surface. The best reconstruction of coastal bathymetry of the test site in Kuala Terengganu, Malaysia, was obtained with polarised L and C bands SAR acquired with HH and VV polarizations, respectively. With 10m spatial resolution of TOPSAR data, an accuracy of (root mean square) ± 7.23m was found with LHH band.
