| 摘 要： | 通过拓扑结构的分析,提出了一种针对拖线阵声纳的数字式水下数据高速传输的方案;介绍了水下数据传输节点的总体设计,并详细地介绍了HOTLink发送接收控制器的设计;然后设计了基于伪随机序列码的误码分析仪,并用其测试了水下数据高速传输节点的误码率。误码测试结果和性能比较结果表明该方案切实可行,并能够方便地实现小型化。

| Abstract: | In this paper, a scheme of underwater acoustic digital high-speed transmission for towed arrays is proposed. We analyze and build the underwater digital high-speed transmission topology that suits towed arrays, and introduce the system design of transmission node. Additionally, we design control logic of HOTLink Transmitter/Receiver on FPGA and test the bit error rate (BER) of transmission node. The low BER and comparison with ATM node show that the transmission node is feasible. It is an easy way to realize miniaturization of the towed array system. |
