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 and 15bps 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.
