Research on Route Planning Model Based on Multi-beam Sounding Technology

Abstract

With the advancement of multi-beam sounding technology, designing an effective aerial survey route has become a crucial research area. This research aims to address the line layout problem for multi-beam sounding in various oceanic regions through the proposed route planning model. Firstly, analyze the functional relationship between the depth of seawater, the coverage width of the measurement line and the overlap rate between adjacent strips under the condition of different distance from the center point of the measurement line. Secondly, describe the coverage width of multi-beam sounding at different positions using trigonometric functions based on a stereoscopic model of the ship's cross-section at any course. Finally, under the condition of fixed gradient of seabed slope, the design and solution of aerial survey routes in the sea area is carried out by using the ox-ploughing reciprocal method, and the route planning model is established with the goal of achieving the maximum coverage area and the minimum distance of aerial survey and the aerial survey plan of the sea area is given.
