Abstract

Abstract

A new high precise source of data has recently become available using multibeam sonar systems in hydrography.The multibeam sonar systems can provide hydrogr aphic quality depth data as well as highresolution seafloor sonar images.The seafloor backscatter strength data of each beam are utilized from the multibeam sonar and the automatic classification technology,so that the seafloor type identification maps can be got.To analyze all kinds of error effects in backscatter strength data is based on the relationship between backscatter strength and seafloor types.Analyzing the influences of local bottom slope and near nadir reflection in backscatter strength data is emphasized on and the correction algorithms and results of these two influent factors are also given.After processing the raw backscatter strength data and correcting error effects,the processed backscatter strength data can be got which only reflect the features of seafloor types.Applying to the processed backscatter strength data and mosaicked seafloor sonar images,seafloor classification and geomorphy interpretation are engaged in.
