摘　　要：为了满足水下探测机器人(ROV)的工作需要,实现其在堤坝、码头及港口等复杂环境的高精度定位,设计并且实现了一种基于短基线的高精度ROV定位系统。该定位系统采用高频宽带调频信号和先进的自动校阵技术来提高定位精度,运用高速处理芯片实时显示定位信息。水池及外场海试等工程实验表明,该系统具有精度高和适应性强的特点,证明该系统技术路线可行且性能可靠。A short baseline positioning system was designed and implemented for underwater remotely operated vehicles （ROV） according to their working requirements in dam and dock applications. The high-frequency broadband posi-tioning and automatic calibration technology were applied to the system to improve the positioning precision. A high-speed digital signal processing chip was used to real-time display the positioning information. The pool experiment and sea test verified the system＇ s high accuracy and good adaptability, and proved that it is feasible in technique and reliable in performance.
