摘要

利用无线传输技术从海底平台向中继浮标传输数据正成为海底平台数据检索的主要方法，与水下光波或电磁波相比，通过水下声波传输数据具有一定的优势。水听器在水下声波传输中起着至关重要的作用，基于共振腔的低成本、小型化、高灵敏度水听器满足了海底平台数据检索场景的需求。本文提出了一种用于水下声学数据传输的多共振腔水听器。通过理论分析和仿真研究了腔体的声共振特性。设计和制造了一个八层球形腔体水听器，并模拟和测试了水听器的声学传感特性和性能。最后，在湖泊中使用所提出的水听器进行了水下声学数据接收测试，证明水听器能够准确接收波特率为 145.45 bps 的声学数据，且无误差。

Multi-resonance-cavity hydrophone for underwater acoustic data transmission

Transmitting data from the seabed platform to relay buoys using wireless transmission techniques is becoming the main approach for seabed platform data retrieval, and data transmission via underwater acoustic waves offers certain advantages compared to that via underwater optical or electromagnetic waves. Hydrophones play a crucial role in underwater acoustic transmission, and low-cost, miniaturized, high-sensitive hydrophones based on resonance cavity meet the demands of seabed platform data retrieval scenarios. This paper proposes a multi-resonance-cavity hydrophone for underwater acoustic data transmission. The acoustic resonance characteristics of the cavity is studied through theoretical analysis and simulations. An eight-layer spherical cavity hydrophone is designed and fabricated, and the acoustic sensing characteristics and performances of the hydrophone are simulated and tested. Finally, underwater acoustic data receiving tests using the proposed hydrophone are conducted in a lake, demonstrating the hydrophone’s ability to accurately receive acoustic data at the baud rate of 145.45 bps with no error.
