无线遥控、浮标式水下目标跟踪定位系统

设计了一种新型的水声定位系统克服传统长基线定位系统操作复杂、工作效率低等弱点。通过在海上布放浮标阵,在较大范围内监测目标运动信息;组建海上无线局域网络实现浮标与基站的数据交换;加装DGPS接收机,动态获得浮标的大地坐标,用于水下目标位置的解算。系统已通过了海试,试验结果表明系统具有作用距离远,定位精度高,操作简便等优点,其可行性及可靠性也得到了验证。

Design of wireless acoustic buoy array multi-targets tracking and positioning system

An underwater target tracking and positioning system is designed to overcome the deficiencies of the traditional long-baseline positioning system, such as complicated operation and low efficiency. The system detects the movement information of targets in a large range by the buoy array disposed on the sea, exchanges data between base station and buoys through the wireless local network built on the sea, and obtains the geodetic coordinate of buoys from the DGPS receiver integrated in the buoy, which is used to calculate the position of an underwater target. The system has been successfully verified by the test carried out on the sea, which shows that this system has many advantages, including large effective range, high positioning accuracy and simple operation. Its feasibility and reliability have also been proved.
