机载激光测深仪（ALB）采用高采样率和点密度测量浅水。因此，可以避免在不可接近的区域中使用传统检测方法的问题。本研究的重点是接收回波信号，识别目标回波，并在沿海环境中整合陆地和水下地形点云数据的实用解决方案。本文以作者在深圳大学研制的单波段ALB系统为基础，对系统设计和数据处理方案进行了优化，以提高接收系统的性能。在海南岛东部进行了飞行试验，验证了所提策略的有效性。最后，总结了自主研发系统的技术特点，为后续相关海洋光探测与测距（LiDAR）激光系统的产业化生产提供了可靠的参考来源。
Airborne laser bathymetry (ALB) is employed to measure shallow depth water by using a high sampling rate and point density. Thus, the problems of using traditional detection methods in inaccessible areas can be avoided. This study focuses on practical solutions for receiving echo signals, identifying target echoes, and integrating land and underwater terrain point cloud data in coastal environments. Optimization of the system design and its data processing scheme is undertaken to improve the performance of the receiving system based on a single-band ALB system developed by the authors at Shenzhen University. A flight experiment over eastern Hainan Island was conducted, during which the effectiveness of the proposed strategy was verified. Finally, the technical characteristics of the self-developed system are summarized to provide a reliable reference source for the subsequent industrialization and production of related marine light detection and ranging (LiDAR) laser systems.
