Evolution and Future of Multibeam Echosounder Technology
2007 Symposium on Underwater Technology and Workshop on Scientific Use of Submarine Cables and Related Technologies, 2007The MultiBeam Echo Sounder (MBES) has become an important tool in oceanic applications such as seafloor mapping, sediment evaluation, sub-bottom profiling, surveys, fisheries research, mine countermeasures, and underwater inspections. Intense interest has been directed toward improvements in performance, and new concepts are being introduced at a rapid

Measurement of Scattering Properties of Water Body by Using a Multibeam Echosounder System
IEEE Transactions on Instrumentation and Measurement, 2023We propose a backscattering compensation-based procedure to enhance the performance of multibeam echosounder systems (MBESs). High resolution in a wide field of view is the main benefit of MBESs, and this property makes them increasingly important for ...

High-resolution interferometry for multibeam echosounders
Europe Oceans 2005, 2005Two main approaches are met today in swath bathymetry sonar systems. Interferometric sidescan sonars use the phase difference between two (or more) close receivers to estimate the arrival angle of instant signal. Multibeam echosounders (MBES) use beamforming methods (prior to amplitude or phase detection) in order to obtain an intrinsic spatial ...

When backpropagation neural network (BPNN) is often applied to supervised classification, problems arise, including a slow convergence rate, local extremum, and difficulty in determining the number of hidden layers and hidden nodes that affect the ...

Seabed classification using multibeam echosounder
2008 1st International Conference on Information Technology, 2008The method of seabed identification and classification from multibeam sonar echoes is presented. The proposed approach is based on calculation of a set of parameters of an echo envelope, similarly as in seafloor classification using single beam echosounder.

Roughness parameters imaging with a multibeam echosounder
The Journal of the Acoustical Society of America, 2017The aim of the study is to perform quantitative imaging of the seafloor random parameters using a multibeam echosounder. More specifically we present in this communication a focus on the interface roughnesses with controlled parameters using a 3D modeling of a layered media with rough interfaces.

Qualitative and Quantitative Description of Multibeam Echosounder Systematic Errors on Rocky Areas
Marine Geodesy, 2012 WOSInternational audienceThis paper deals with the problem of systematic depth errors made in surveying dumped rocks with multibeam echosounder. These errors may induce dangers for navigation in very shallow water areas, or huge costs for coastal ...

Methods of Multibeam Echosounders Resolution Increasing
2006The methods of resolution increasing were considered in this work. These methods are applied to the samples of experimental data as well as model data. The results obtained can be compared with ones are found by the standard DFT processing.

Multibeam echosounders have revolutionized our ability to resolve seabed geomorphology and regionally define its substrate. Using a fan of narrow acoustic beams, the slant ranges, angles and returned backscattered intensity can be employed to define the seabed elevation and infer the substrate.
