Abstract:

Multi-beam bathymetry system can give dozens or even hundreds of depths in a plane vertical to the track one time,and obtain a full-depth water depth swath with a certain width,thus it greatly improves the oceanographic surveying efficiency.The basic principle of multi-beam bathymetry system is introduced in brief.Then the deep-sea multi-beam bathymetry systems of L3 ELAC Nautik,Teledyne(ATLAS),and Kongsberg are systematically introduced,and domestic development is also analyzed.Finally,the development trend of deep-sea multibeam bathymetry system is prospected,such as higher bathymetry resolution and accuracy,larger coverage,stronger water column profiling and more convenient data processing.
