Research and Simulation of Satellite Communication Channel for Ship Rolling in Sea Waves

This paper realizes the satellite communication channel modeling research of ship rolling in the sea with wind and wave Since ship rolling may cause the terminal antenna to be inaccurate to the star, thus affecting the quality of satellite communication, we constructed a ship rolling model, and combined the periodic rolling angle with the satellite antenna pattern. The antenna gains variation rule of ships rolling under different ocean waves was simulated, and the channel model was generated in combination with the channel simulator. Finally, the real satellite terminal and satellite signal were used for simulation experiment, and it was found that the communication quality was very good under light waves, and it is a intermittent communication during medium waves, but the terminal could not communicate during strong waves.
