摘要
侧扫声呐系统因可连续、全覆盖地获取海底地形和水下目标的声学图谱影像,在海洋测量、海洋工程勘探和水下考古等领域得以广泛应用。本文以大连西沙坨子周边海域的人工鱼礁投礁区为实例,在网络RTK技术的支持下,详细介绍了侧扫声呐系统探测人工鱼礁的方法和过程,并将侧扫测量结果与投礁区投礁前的海底地形侧扫数据进行了对比,同时,与投礁后潜水员下潜投礁区拍摄的影像资料进行了印证。结果表明,该方法获取的侧扫声呐声学图像不仅能直观、形象、准确地对人工鱼礁进行判读和提取,还能确定人工鱼礁的空间位置和掌握人工鱼礁在海底的空间布局,是一种行之有效的人工鱼礁探测方法。
The side scan sonar system is widely used in marine survey, marine engineering exploration, and underwater archaeology for continuous and full coverage accession of the seafloor terrain and underwater target's acoustic map. Take the surrounding artificial fish reef area of Dalian Xisha island as example, in the present study, we give a detailed introduction of the detecting steps and process of scan sonar detection system when detecting artificial fish reefs based on network RTK technology. We compared the side scan measurement data before and after artificial reefing. We also compared the data obtained from field picture recording and side scan. The results show that the side scan sonar acoustic image technology can not only visual and accurate interpretation and extraction of artificial reefs, but also determine the spatial layout of the space position of artificial reef and master artificial fish reef on the seabed, and therefore be considered as a kind of effective artificial reef detection method.
