多波束测深系统在海底特征地物测量中的应用

Application of Seafloor Characteristic Feature Measurement on Multibeam Bathymetric System

受限于水下环境的复杂性和地形的非结构化,传统测量手段难以获取高精度的海底特征地物信息。以EM2040多波束测深仪为例,首先介绍了多波束测深系统的基本原理、软硬件构成,并给出一种利用多波束测深的实施方案。系统检校后在舟山某海域海底特征地物测量中进行勘测,最终获得高质量的地形成果。通过选取局部特征地物成果进行分析,显示出该系统在海底特征地物测量应用中的优势,但也存在着一定的局限性。研究成果可为海洋生态环境及相关工程技术人员提供基础资料,具有一定的应用价值。

Limited by the complexity of the underwater environment and the unstructured terrain,it is difficult for traditional surveying methods to obtain the high-precision information about the features of the sea floor.Taking the EM2040 multibeam sounder as an example,the basic principle,software and hardware configuration of the multibeam bathymetric system are first introduced,and an implementation scheme using multibeam sounding is given.After the system calibration,the survey was carried out in the survey of submarine features in a certain area of Zhoushan,and finally the high-quality terrain results were obtained.By selecting and analyzing the results of local features,it shows that the system has strong performance in the application of surveying features of subsea features,but it also has certain limitations.The research in this article provides the basic information for marine ecological environment and related engineering and technical personnel,and has good application significance.
