摘要
现如今单波束测深系统及多波束测深系统已经在长江河道水下地形测绘中广泛应用,人们对于内河航道水下地形数据的精度要求也越来越高,声惯一体单波束测深系统很好地解决了传统单波束测深精度不高及多波束测深系统安装操作复杂且对测量水域条件要求较高等问题。本文针对声惯一体单波束测深系统在长江河道勘测中的实际应用情况,与传统单波束及多波束测量数据进行对比分析,结果表明声惯一体单波束测深系统能够很好地满足长江河道高精度测量的需求。
Nowadays,the single-beam bathymetric system and multi-beam bathymetric system have been widely used in the underwater topographic mapping of the Yangtze River,and people have higher and higher requirements on the accuracy of underwater topographic data of inland waterways.By using the single-beam integrated with inertial navigation system(INS)bathymetric system,the problem of low precision of traditional single-beam,complex installation and operation of multi-beam system and high requirement of water condition is solved well.In this paper,the practical application of single-beam integrated with INS bathymetric system in the survey of the Yangtze River channel is compared with the traditional single-beam and multi-beam survey data.The results show that single-beam integrated with INS bathymetric system can meet the demand of high precision survey of the Yangtze River channel very well.
