摘要
海水声速是多波束测深系统进行水深测量的基本参数之一 ,声速剖面正确与否直接影响测量结果的精度和可靠性。本文阐述了声速对多波束水深测量的影响机理 ,并通过对南海 SA1 2试验区采集的声速资料的分析 ,以 Sea Beam2 1 0 0多波束测深系统为例 ,对声速校正的技术方法进行了探讨。
The seawater sound velocity is one of the basic parameters that multi-beam echo sounding 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, the mechanism that sound velocity influences multi-beam sounding was expatiated. According to the analysis about sound velocity data collected in the Block SA12 of the South China Sea, the technical method of sound velocity correction was discussed by the example of SeaBeam 2100 Multi-Beam Bathymetric Sonar System.
