基于光电阵列的水下定位通信一体化系统设计

Design of underwater positioning communication integrated system based on photoelectric array

针对无人潜航器(UUV)在水下容易受复杂环境的干扰而造成相对光源姿态偏转,使定位与通信受影响的问题,提出了一种基于曲面阵列的水下定位通信方案,依此方案设计了一套基于现场可编程门阵列(FPGA)为处理核心的水下定位通信系统,并对系统进行了测试。测试结果表明:此系统能够精确估计出接收端相对光源的姿态并做出调整,在调整姿态后其通信性能具有明显提升。

For the problem that unmanned underwater vehicle(UUV)is easy to be interfered by the complex environment,which results in relative light source attitude deflection and affects positioning and communication,an underwater positioning communication scheme based on curved surface array is propseed,and a set of underwater positioning communication system based on field programmable gate array(FPGA)is designed and tested.The test results show that the system can accurately estimate the attitude of the receiver relative to the light source and adjust it.After adjusting the attitude,the communication performance of the system is improved obviously.
