ABSTRACT

The multibeam bathymetry technology measures water depth strip by transmitting multiple beams through transducer, which is more efficient and accurate than the traditional bathymetry methods. In this paper, we focus on the measurement of the bathymetry of the sea area by multibeam sounding line. Firstly, we establish a two-dimensional discretization model to describe the relationship between the coverage width and the overlap rate of multibeam sounding. Secondly, we develop a three-dimensional mathematical model of the coverage width of the sounding vessel when facing the tilted seabed. Finally, by constructing the geometric model and single-objective optimization model, the shortest survey line planning scheme is given for the multibeam sounder while meeting the requirements of coverage and overlap rate. Through the construction of the above model, this paper draws the following conclusions: ① The distribution density of the survey line should be negatively correlated with the depth of the sea; ② Sailing along the isobath maximizes the width of the survey; ③ To achieve the shortest survey line, the direction of survey lines should always be parallel to the isobath.
