设计了一套集导航、定位、无线电通信和水声遥控通信功能于一体的大型联合系统。利用试验船上的船载测距仪、海面的无线电遥控浮标、海底应答器阵、无线电基站和显控计算机组成的空间立体网络实现了对水下目标的导航、定位功能，具有三维测量能力；通过无线电通信和水声遥控通信相结合的方法，实现了对海底应答器的远程控制和管理，增大了系统的工作范围；提出一种实用有效的海底应答器阵位测量方法。文中主要介绍了系统的总体设计方案、导航定位原理、水声信号处理方法和试验结果。海上试验结果证明了系统的可行性和可靠性。

Research on the Incorporate Technology of Distributed Underwater Navigation, Orientation and Comunication

A large-scale combined network was proposed to position and navigate the underwater ma?neuverable objects by both the wireless radio communication and the underwater acoustic remote con?trol communication. The system can track the underwater object’s three-dimensional movement by the cooperation of the shipborne range finder, the surface radio remote buoy, the underwater transponder array, the radio base station and the display control computer, and control the remote underwater transponder by the combination of radio and underwater acoustic remote control communication and extend the systemic work range. A practical method of the underwater transponder array measuring was presented. The general design scheme, the theory of the underwater orientation and navigation, the method of signal processing were given. The results of the lake and sea trials show that the system is feasible and reliable.
