Abstract
In the aspect of seafloor sediment detection, underwater acoustic method has been concerned and used because of its high working efficiency and continuous abundance of data, and the processing function of echo intensity data is to obtain backscattering intensity data which only reflect the change of seafloor sediment. However, relying solely on multi-beam bathymetric system or scanning Sonar will lead to awkward situations where the resolution is insufficient or topographic factors affect the effective removal. In this paper, the purpose of this paper is to reconstruct the sound intensity of side scan sonar in the same area by using the seafloor terrain data obtained by multi-beam bathymetric survey, and then to form a sonar image which eliminates the influence of terrain. This paper discusses how to deal with the directional scattering intensity data of many kinds of data sources, such as multi-beam bathymetric system and scanning Sonar, so as to provide a service for the effective classification of seafloor sediment.
