Abstract
A digital bathymetry model according to principle of multi-beam bathymetric sonar system is designed, and a correction method of water depth survey due to effect of angular beamwidth is given. Accordingly, terrain maps are constructed to mimic the realtime terrain. The model and correction are verified by using practical water depth data of certain seafloor. Simulation results show that the model is in accordance with theoretical analysis and practical situation, and the correction effect of water depth is obvious.
