Abstract: According to the wireless wave propagation and microwave channel modeling in typical sea conditions, a microwave wireless channel model on two dimensional sea surface in a random environment is established in this paper based on the modeling theory of stochastic bridge for fixed communication environment simulation. Firstly, based on the P-M spectrum of the sea surface wave, electromagnetic simulation models in sea conditions ranging from 0 to 6 grade have been established. Then, by analyzing the random ray sample data collected under different sea conditions, the digital characteristics of key parameters of stochastic bridge processes are determined, and the microwave band stochastic multi-path channel model on sea surface is constructed. Finally, the analysis of radio wave propagation characteristics is conducted using the proposed channel model. The simulation and laboratory experimental data show that the characteristics of the proposed channel model are in agreement with tested results. In brief, this paper provides a valid theoretical method and technique proposal for the modeling and simulation of the received waveform of key electronic equipment on ship in complicated electromagnetic environment.
