Study and Application of Optimization Model on Survey Line under Multibeam Bathymetric System

In this paper, the definition of overlap rate is deduced so as to clarify the influence of overlap rate between the horizontal plane and the slope on the multibeam line measurement problem, and the artificial correction is calculated by taking the average value of the coverage widths of the two times before and after. The expressions for the coverage widths of different lines and their corresponding water depths, slope inclination angles, and transducer opening angles are derived from the functional relationship by combining numerical and morphological methods. The resulting expression of the coverage width W was corrected, averaged and brought into the definition of the overlap rate, resulting in the final expression to calculate the corresponding value, and the resolution and accuracy of the data results were high.
