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.
