摘　　要：针对多波束水位改正依赖国外商用软件的问题,通过总结常用的水位改正方法,结合实际工作需求,在VS2010平台下基于VC++进行了多波束水位改正软件的国产化开发。软件实现了距离加权内插法、时差法、最小二乘拟合法等水位改正方法,将水位改正工作根据实际情况分为单站、双站、三站和多站模式,提出利用TIN网实现多站水位的交互式、批量化处理,对于推动国内多波束水位改正理论研究及工程应用具有一定的实际意义。Nowadays,multibeam water level correction most- ly depends on the foreign commercial software. Combining with the actual work requirements, this paper summarizes the common water level correction method and develops a do- mestic multibeam water level correction software in VS2010 platform based on VC＋ ＋. The software realizes to correct water level with the method of distance-weighted interpola- tion, time difference, least square fitting, etc. And the water level correction work in accordance with the actual situation was divided into the single station, two stations, three sta- tions and multistation mode. It proposes to use TIN network to achieve interactive multistation water level and batch pro cessing,which has an important practical significance to pro- mote theoretical research and practical application of multibeam water level correction in China.
