随着人类对海洋的逐渐深入开发,水下多平台作业的需求日益显著,而平台间的相互位置关系是确保作业效能的重要信息。为此,本文分析了基于声学超短基线定位技术的位置测量方法,分析了声传播特性、定位工作原理、误差源及主要误差模型,通过历史环境参数和仿真分析的方式开展了定位精度和作用距离分析。在此基础上,以水下作业的典型应用场景,在不同接收发射深度下,论文分析后给出了最优的协同定位策略,有助于指导水下协同作业。
With the gradual in-depth development of the ocean, the demand for underwater multi-platform operation is becoming more and more significant, and the mutual position relationship between platforms is an important information to ensure the efficiency of the operation. Therefore, this paper analyzes the position measurement method based on acoustic ultra-short baseline positioning technology, analyzes the acoustic propagation characteristics, positioning working principle, error sources and main error models, and analyzes the positioning accuracy and distance by means of historical environmental parameters and simulation analysis. On this basis, based on the typical application scenarios of underwater operations, the optimal co-positioning strategy is given after analysis at different reception and emission depths, which is helpful to guide underwater cooperative operations.
