ABSTRACT

This study focuses on optimizing multibeam bathymetry technology, applying it to underwater terrain measurement, achieving a transition from point-to-line measurement, and minimizing the measurement path. Using the sine theorem and slope cosine theorem, a mathematical model for coverage width in the presence of slopes is established. The study calculates the seawater depth, coverage width, and overlap rate with the previous measurement line at various positions along the measurement line from the center point, with a distance of 800m resulting in a seawater depth of 49.05m and a coverage width of 170.27m. Subsequently, multiple β angles are selected to quantitatively analyze the impact of different angles on the measurement. Combining the established coverage width model, a mathematical model for coverage width at a certain distance from the center of the maritime area is developed for different β angles. The conclusion is drawn that at a β angle of 180 degrees, the farthest point from the center of the maritime area has the minimum coverage width of 63.03m, while at a β angle of 0 degrees, the farthest point has the maximum coverage width of 770.07m.
