摘要
单波束测深仪是现代海洋测量尤其是内河水下地形测量中的主要测量仪器。即使在声速设定正确的前提下,单波束测深仪的观测值仍然会有各类型的粗差。针对其原始水深值粗差处理问题,创新性地提出"地形链"的概念,设计了一种新的针对单波束测深仪水深观测值的粗差检测与修正算法,针对长江流域的单波束测深数据进行处理,结果表明算法对各类粗差有明显的检测和修正效果。
The single beam bathymeter is an important equipment of underwater terrain surveying in the ocean and especially in the fiver. Even though the speed value of the sound is set correctly, the depth value may still be the gross error as result of other measurement factors. This article originally presents the concept of terrain chain and a novel algorithm of water depth gross error detection and correction based on the terrain chain concept. The performance of processing several water depth dataset collected by a single beam bathymeter in the Changjiang River shows the obvious effect on gross error detection and correction.
