无人船与机载雷达技术在水下地形测绘中应用

Application of Unmanned Ship and Airborne Radar Technology in Underwater Topographic Mapping

针对地上河流的水资源对经济发展所起的作用日益增加,对河流水资源的开发、治理等工作变得尤为重要。随着科学技术的发展,单波束技术、多波束技术,激光雷达技术的融合实现了水下地形测绘任务。依托河流某一项目,证明了这几种技术在获取水下地形数据方面的可行性,并依托该项目系统地介绍了水下测绘的完整流程。并为大规模开展类似项目提供参考依据。

In view of the increasing role of water resources in the Yangtze River Basin in economic develop-ment, the development and management of water resources in the Yangtze River has become par-ticularly important. With the development of science and technology, the integration of single beam technology, multi beam technology and lidar technology has realized the task of underwater topo-graphic mapping. Relying on a project in the Yangtze River Basin, this paper proves the feasibility of these technologies in obtaining underwater topographic data, and systematically introduces the complete process of underwater surveying and mapping based on the project, and provides refer-ence basis for large-scale similar projects.
