Abstract：Traditional multibeam bathymetry system based on FT beamforming method can not achieve high accuracy seafloor bathymetry estimation of outer beams area, while interferometric multibeam bathymetry system based on phase detection method can estimate the bathymetry information in such area with high accuracy and resolution ability. To improve the performances of traditional multibeam bathymetry system, MSB-RMU algorithm is proposed, combining the advantages of FT beamforming and phase detection methods, which has high spatial resolution ability and achieves high accuracy bathymetry estimation of both central beams area and outer beams area. The processing results of experiment data prove the efficiency, practicality and superiority of the new algorithm, which ensures the first domestic multibeam bathymetry system to achieve 6 times coverage of the water depth.
