Abstract
Seafloor mapping using acoustic remote sensing technique is an attractive approach due to its high coverage capabilities and limited costs. The Multi-Beam Echo-Sounder (MBES) system provides high-resolution bathymetry and backscatter information with relatively perfect coverage. This paper described how the MBES system works and with the objective to get simulation images of it. The main theory of this thesis is sonar equation. The backscatter target strength is what we really needed. We present a simulation of seafloor mapping through backscatter data per beam, and because its performance is sensitive to seafloor type variation along the MBES swath so corrections for the angular dependence are applied. This simulation can support a wide range of survey applications including: hydrography, search and locate, route survey and seafloor characterization. Also, a further discussion such as the doppler effect and sound speed correction should be discussed in the future.
