摘要
为探讨多波束测深系统在长江河道测量中的适用性,在阐述多波束测深系统工作原理及工作过程的基础上,从测量方式、数据处理模式及成果形式等方面比较了传统单波束测深仪与多波束测深系统的差异。并通过采用两种测量方式同步施测,获取同一区域水下数据进行对比。结果表明:多波束数据精细度优于单波束,成果形式更多样化,但便捷性上略逊于单波束测深仪。
In order to discuss applicability of multi-beam sounding system in hydrographic survey of the Yangtze River,on the basis of introducing principle and process of multi-beam sounding system,this paper compared differ⁃ences between traditional single beam bathymetry and multi-beam system from aspects of measuring mode,data pro⁃cessing mode and result form.Underwater data in the same area were obtained through simultaneous measurement of the two methods.The results showed that data of multi-beam sounding system was better than that of single beam bathymetry,and result forms of multi-beam sounding system were more diversified.However,single beam bathyme⁃try is more convenient.
