Inertial navigation system (INS) is an independent navigation system, but is difficult to be used in far-distance and long-time navigation due to INS accumulation error. Thus, a new synthetic navigation system for underwater based on the integration of INS and multibeam bathymetric system (MBS) is studied and presented in the paper. Firstly, we introduce the composition of the underwater navigation...
Precise determination of transducer instantaneous height of multibeam bathymetric system (MBS) is a very important work in fulfilling the transformation from the MBS sounding data to the underwater topographic height. The blend of GPS height and heave can get accurately the solution. But it is a key to design an optimum filter for implementing the blend. In this paper, we study in detail the method...
The multibeam bathymetric system (MBS) can provide both sounding data and acoustic backscattering strength data. Using the latter, Seabed classification can be fulfilled. This paper presents a method of seabed classification based on self-organizing feature maps (SOFM) neural network. The complete theory and data processing procedure are researched in detail. Some valuable conclusions are drawn through...
