摘　　要：基于长基线水下航行器定位导航系统的工作原理,设计并实现了一套可独立完成水声询问信号发射、水声遥控指令编码及发射控制、应答信号接收及处理、时延估计及数据传输控制等多功能的水声收发机,论述了水声收发机中信号检测、时延估计等信号处理关键技术,介绍了软、硬件设计思想和实施方案,并给出了该套系统经过模拟器、湖试和海试的试验结果。试验结果表明,该系统性能可靠、功能完善,具有一定的工程应用价值。Based on the operation principle of the long-base-line underwater vehicle navigation and positioning system, a multi-functional acoustic transceiver is proposed, which can be used for sending acoustic interrogation signal, controlling the coding and sending of acoustic control command, receiving and processing the signal from transponders, estimating time-delay and transmitting data. The key techniques of signal processing are explained, such as signal detection and time-delay estimation. The design thought and implementary scheme of the sohware and hardware design are introduced. The test results obtained by electricity simulator and experiments in lakes as well as at sea show that the multifunctional acoustic transceiver has stable performance and comprehensive function and can be used in practical project very well.
