State of the art in seafloor acoustic remote sensing using multibeam echo sounders

초록

This paper introduces current trends in seafloor mapping data acquisition using multibeam echo sounders, presents a general procedure of processing both bathymetry and sonar data, and indicates some new directions for ocean mapping in the future. It also describes a state of the arts in Korea in post-processing and visualizing multibeam bathymetry and sonar data for the purpose of developing ocean mapping systems. In particular, an algorithm of enhancing multibeam sonar data is proposed and the experimental result is demonstrated.
