摘要: 目前采用单波束按照断面法进行水道地形测时，由于测线间没有数据，故在成图时主要通过网格化内插方法实现地形图的连续性，这样会导致地形通过内插平滑而受到歪曲、夸大或抑制。而多波束测深系统属于面状测量系统，为验证多波束的技术特点，技术人员对单位引进的多波束系统进行了对比试验及分析。试验选取了平面区域和护岸斜坡区域，通过高、低水时期，利用多波束、单波束以及传统RTK 等测量模式，进行对比试验研究，得出一些结论，为多波束测深系统推广应用提供科学参考。
Abstract: Single-beam topographic survey in accordance with cross-sectional method is mainly used to achieve the continuity of topographic map by grid interpolation because there is no data between the lines, which will lead to the distortion, exaggeration or suppression of the terrain through interpolation smoothing. The multi-beam bathymetric system belongs to the planar measurement system. In order to verify the technical characteristics of multi-beam, the technicians conducted comparative tests and analysis on the multi-beam system. The plane area and revetment slope area are selected in the experiment. By using multi-beam, single-beam and traditional RTK measurement modes in high and low water periods, some conclusions are drawn, which can provide scientific reference for the popularization and application of multi-beam bathymetric system.
