多波束倾斜安装技术在水下检测工程中的应用

由于常规多波束系统垂直安装，无法精确测量临岸水域、码头、防波堤、丁坝、海岛礁等特殊水下地形地貌。针对这一难题，进行了多波束倾斜安装和校准的技术研究。采用多波束倾斜安装的方法，增加相关侧的波束数量，测量能够达到吃水线位置。水深成果精度满足规范及工程需求，实现了水下特殊地形地貌的全覆盖测量，为水上水下一体化模型提供技术支撑，可以广泛应用在水下检测工程中。

Application of multi-beam tilt installation technology in underwater detection engineering

Due to the vertical installation of conventional multi-beam systems,it is impossible to accurately measure the special underwater topography such as coastal waters,docks,breakwaters,spurs,islands and reefs.In response to this problem,technical research on multi-beam tilt installation and calibration is carried out.The method of multi-beam tilt installation is used to increase the number of beams on the relevant side,and the measurement can reach the position of the waterline,so the accuracy of the water depth results can meet the specifications and engineering requirements.The whole coverage survey of underwater special topography is realized,which can provide technical support for the integrated model of water and underwater,and can be widely used in underwater detection engineering.
