多波束水深测量马修斯法辅助声速剖面改正

马修斯法是单波束水深测量声速改正的常用方法,为了提高多波束水深测量声速改正精度,利用马修斯方法的参数,在该方法基础上推导出新的改正公式,并将之运用在多波束水深测量中的声速剖面重构;实验表明,该方法略优于水文内插法;与纯数学拟合外延方法相比,具有明显优势;运用该方法可以得到效果更好的海底三维图,提高多波束水深测量精度和作业效率。

Auxiliary Method of Multi-beam Echosounding Sound Velocity Profile Correction via Mathews

The method of sound velocity correction via Mathews is used in single-beam echosounding usually,in order to improve the precision of sound velocity correction of multi-beam echosounding,a new correction fomula is deduced using the parameters of Mathews,and is applied to sound velocity section reconstruction.This method is better than method via hydrology interpolation;compared with data fitting and expanding according to mathematics,it has more advantages obviously.The seabed 3D impression drawing through this method is better,and it can improve measure precision and work efficiency at multi-beam echosounding.
