摘要
新版国际海道测量标准明确规定特等和1a等测量时必须实现全覆盖测量。为此,提出基于全覆盖测量的船速控制方法。研究表明:满足全覆盖的船速与多波束换能器的扇区宽度、纵向波束宽度和声速有关。另外,考虑到海底地形的精确获取是未来海道测量的主要方向,提出了基于海底地形分辨率的船速控制方法。在此基础上,兼顾测线间距选取,进一步提出基于海底地形分辨率的测船船速与测线间距综合优化选取方法。方法兼顾了全覆盖和海底地形分辨率的需求,体现了逐步优化设计的思想,符合测量实际,仿真实验也验证了该方法的有效性。
The 5 th Edition of IHO S-44 specifies the full coverage surveys should be realized in special and la grade surveys. The speed control of the survey vessel based on full coverage survey is presented, and the maximum speed of which is 10 knot.Considering the main direction of the hydrographic surveying in the future is the precise acquisition of the submarine topography, the vessel speed control method based on the seafloor topography resolution is put forward, and the optimization determination of the survey vessel and survey line interval is further proposed.The simulation experiment also verifies the efficiency of the method.
