摘要/Abstract

摘要： 随着多波束技术的快速发展,多波束技术在测深方面的应用也越来越广泛,同时对多波束技术的观测精度也提出了更高的要求。在对SONIC2024多波束的测深系统分辨率模型的基础上,对精细化崩岸监测进行了参数设计研究,分别得出了横向、纵向分辨率的分布规律,推导出了采样率、发射角、最大有效航行速度、扇面开角等参数关系及推荐值,分析了探测精度与水深和发射角的关系、扇面开角与横向分辨率的关系、SONIC2024测深系统纵向分辨率优于横向分辨率等结论。这些结论可作为多波束扫测前对关键参数进行技术设计的依据。最后总结得出了参数的设计流程,并在精细化崩岸监测中对这些参数设置提出了相关建议。

Abstract: The multi-beam technology is extensively applied in bathymetry, which in turn poses higher requirements for the observation accuracy of multi-beam technology. In this paper, the parameters of fine monitoring of bank collapse are designed and studied based on the resolution model of SONIC2024 multi-beam sounding system. The distribution rules of lateral and longitudinal resolutions are obtained respectively. The relations and recommended values of parameters inclusive of sampling rate, emission angle, maximum effective navigation speed, and sector’s opening angle are deduced. It is concluded that the vertical resolution of SONIC2024 sounding system is better than the lateral resolution. The conclusion can be used as the basis for the technical design of key parameters before multi-beam measurement. Finally, the process of designing the parameters is summarized, and some suggestions for setting these parameters in the fine monitoring of bank collapse are put forward.

Key words: multi-beam sounding system, bank collapse survey, sampling rate, sounding resolution, beam angle, maximum effective navigation speed, sector’s opening angle
