摘　　要：现有的跨空海界面通信方式都存在着各自的问题,磁感应通信具有信道特性稳定、抗时变环境等优点,使得其很适用于跨空海界面环境。本文对跨空海界面磁感应通信进行研究,利用分层导电媒质中的磁偶极子,建立跨空海界面磁感应传输模型,仿真磁场分量的传输特性;借助于磁感应通信系统,进行海上通信验证试验。结果表明:经相关信号处理后,实现了35 m水深、速率15 bps的无误码通信,验证了磁感应通信在复杂海洋环境中的可行性和有效性,为进一步跨空海界面磁感应通信的研究打下基础。The Existing communication methods have their own problems when performing communication from air to sea. Magnetic induction(MI) communication has the advantages of stable channel characteristics and anti time-varying environment, which makes it very suitable for cross air sea interface environment. In this paper, the air-to-undersea magnetic induction(MI) communication is studied. Using the magnetic dipole model of layered conductive medium, the transmission model is established, and the transmission characteristics of magnetic field component are simulated;With the help of magnetic induction communication system, the sea communication verification test is carried out. The results show that after the relevant signal processing, the error free of air-to-undersea magnetic induction communication with 35m water depth and15bps is realized, which verifies the feasibility and effectiveness of magnetic induction communication in complex marine environment, and lays a foundation for the further research of air-to-undersea magnetic induction communication.
