摘要
海水声速是多波束测深系统进行水深测量的重要参数之一。声速剖面的是否正确直接影响测量结果的精度和可靠性。文章从声速在海水中的传播出发,阐述海水中声速的测量,并通过对海区实验数据的分析,对声速的较正方法进行了探讨。
The seawater sound velocity is one of the basic parameters that multi-beam bathymetric system must be used during survey period. The precision and reliability of survey results are related directly to the accuracy of sound velocity profile. In this paper, on the basis of the sound velocity spreaded, the measure that sound velocity was expatiated. According to the analysis about sound velocity data collected in the Sea, the technical method of sound velocity correction was discussed by the example of multi-beam bathymetric system.
