Abstract

This paper introduces a new methods for mapping coastal bathymetry change by using three-dimensional (3D) model from Airborne AIRSAR/TOPSAR Synthetic Aperture data. The new method is based on integration between Fuzzy B-spline and Volterra algorithm. Volterra algorithm is used to simulate the ocean surface current from AIRSAR/POLSAR data. Then, ocean surface current information used as input for continuity equation to estimate the water depths at different locations in AIRSAR/POLSAR data. This study shows that 3D ocean bathymetry can be reconstructed from AIRSAR/POLSAR data. The maximum water depth of 20 m can be captured from TOPSAR data. In this context, these results will be useful to develop a new microsatellite sensor to achieve tremendous advance in coastal navigation and surveying studies with high accuracy data.
