侧扫声呐系统在海岸带测量中的应用
Application of Scanning Sonar System in Coastal Zone Survey

随着我国海洋测绘事业的快速发展，行业内涌现出较多新的技术，侧扫声呐技术在海洋勘测、水下探测等领域的应用日益广泛，展现出巨大的发展前景。声呐技术是一种利用声波在水中的传播特性进行探测和测量的技术手段，具有高精度、高分辨率和远距离探测等优点，受到了广泛关注，在海底障碍物探测项目中取得较好的应用效果。本文通过侧扫声呐技术在海口市城市地质调查项目中的实际应用，划分了海域海底底质类型分布，准确判断了海口市近岸海域海底状况和水下障碍物情况，为海岸带陆海统筹综合地质调查提供海底地形地貌基础资料。
With the rapid development of China’s marine surveying and mapping industry, a variety of new technologies have emerged. Side-scan sonar technology is increasingly widely used in marine surveys, underwater exploration, showing significant development prospects. Sonar technology, utilizing the propagation characteristics of sound waves in water for detection and measurement, offers advantages such as high accuracy, high resolution, and long-distance detection. It has gained widespread attention and demonstrated good application results in seabed obstacle detection projects. This article outlines the practical application of side-scan sonar technology in the urban geological survey project in Haikou City, dividing the distribution of seabed sediment types in the area. It accurately assesses the seabed conditions and underwater obstacles in the near shore waters of Haikou City, providing fundamental data on seabed topography for comprehensive geological surveys of coastal land and sea areas.
