Abstract：The multi-beam technology is extensively applied in bathymetry, which in turn poses higher requirements for the observation accuracy of multi-beam technology. In this paper, the parameters of fine monitoring of bank collapse are designed and studied based on the resolution model of SONIC2024 multi-beam sounding system. The distribution rules of lateral and longitudinal resolutions are obtained respectively. The relations and recommended values of parameters inclusive of sampling rate, emission angle, maximum effective navigation speed, and sector’s opening angle are deduced. It is concluded that the vertical resolution of SONIC2024 sounding system is better than the lateral resolution. The conclusion can be used as the basis for the technical design of key parameters before multi-beam measurement. Finally, the process of designing the parameters is summarized, and some suggestions for setting these parameters in the fine monitoring of bank collapse are put forward.
