摘要 因海冰覆盖和独特的声速剖面特征,北极水声信道有其特殊性,为研究、开发和利用北极,需要开展北极水声通信研究。2017年夏季在北冰洋中心区开展了一次距离1.26km、通信速率为1.2kbps的冰下水声通信实验。实验结果表明通信系统的载波频率偏高、声接收端背景噪声级较高以及水声信道上界面的海冰分布较为复杂是导致实验结果误码率偏高的主要原因,提出了相应的改进措施和建议。实验过程中,水声通信设备系统工作良好无故障。此次实验为极地水声通信装备的研制、极地水声通信的研究与应用积累了宝贵经验。 The Arctic underwater acoustic channel has its particularity due to sea ice cover and the distinctive sound velocity profile of sea water, so it is needed to research the Arctic underwater acoustic communication for the Arctic development and utilization. In the summer of 2017, an underwater acoustic communication experiment under ice was carried out in the central region of the Arctic Ocean, the communication distance is 1.26 km and the communication rate is 1.2 kbps. The experiment shows that for the communication system with a higher carrier frequency, the background noise level at the receiving terminal is high, and the complex ice distribution on the surface of underwater acoustic channel is the main cause for the high bit error rate of the experimental results. The corresponding improvement measures and suggestions are put forward. The underwater acoustic communication equipment works well and has no fault in the experiment. This experiment accumulates valuable experience for the development of polar underwater acoustic communication equipment and for the research and application of polar underwater acoustic communication.
