Abstract
The backscattering intensity collected by multi beam sonar system and scanning sonar system can be used to classify seabed bottom characteristics. However, there are many problems that have not been solved in the practical application. This paper attempts to sort out and analyze the problems encountered in the classification process and put forward some solutions. The relationship among acoustic image, seabed topography and sediment is analyzed
Highlights
side-sweep sonar (SSS)(Side-scan Sonar System) and MBS (Multi-beam Bathymetric System) provide deep water information, and carry sound intensity data back
They correspondingly reflect the texture, fluctuations and seabed bottom characteristics composition of the seafloor. They are important elements for us to understand and utilize the ocean, and are hot issues in the world.And the bottom geology and terrain have a deep influence on the echo intensity.That is, the echo intensity contains the information of seabed bottom characteristics, so we can classify the seabed bottom characteristics, which undoubtedly improves the efficiency of classification compared with the method of submarine sampling
It is necessary to study the submarine reflection model of sound wave, the response mechanism of submarine topography and seabed bottom characteristics to echo intensity and their contribution and separation.And break through the bottleneck of restricting large area, high accuracy and high efficiency geomorphic image acquisition, terrain inversion and seabed bottom characteristics classification.Achieve the integrated acquisition of submarine geomorphic image, terrain and seabed bottom characteristics information based on acoustic intensity echo information

The inaccurate position problem that has puzzled SSS image for a long time in quantifying submarine landform is solved
