Abstract

The major mainstream method for human ocean exploration is to use sound waves to measure water depth. The paper investigates the application of multi-beam bathymetric surveying technology in ocean depth measurement. Traditional single-beam sonar technology faces challenges in survey line design due to dense track lines and lack of data. To address the challenges of multi-beam survey line design below the sea surface, this paper establishes a mathematical model for calculating coverage width and overlap rate through geometric analysis of the beam’s coverage area on the sloping surface. Considering the non-isobath movement of the beam center along the sloping surface, the paper discovered the equivalent relationship between the cross-sectional angle and the horizontal plane. Therefore, a mathematical model for the depth coverage width of multi-beam survey lines was established based on the slope angle and the lateral angle. Based on previous research and relevant references, this paper designed a complete survey line scheme that can fully cover the ideal test area while maintaining a low overlap rate, and verified its rationality.
