Method for realizing maritime microwave directional communication based on Beidou system

The invention discloses a method for realizing maritime microwave directional communication based on a Beidou system. The method comprises the steps of configuring the Beidou system and a microwave system on a ship, and enabling each ship to transmit the respective position back to a land Beidou data center at regular time through the Beidou system; enabling the ship A to send a link request to the Beidou ground data center by using a short message function of the Beidou system; enabling the Beidou ground data center to find out other ships within the directional microwave communication rangeof the ship A and send the position information of the ships to the Beidou system of the ship A; enabling the ship A to select a target ship B to be communicated, adjusting an antenna to point to theship B, enabling the ship A to send a request for linking the ship B and position information of the ship A to the Beidou ground data center through the Beidou system, and enabling the Beidou ground data center to forward the
