摘要：【中文】本发明公开了一种基于北斗系统实现海上微波定向通信的方法，船舶上配备北斗系统和微波系统，各个船舶通过北斗系统定时把各自的位置回传给陆地北斗数据中心；船舶A用北斗系统的短报文功能向北斗地面数据中心发出链接请求；北斗地面数据中心找出在船舶A定向微波通讯范围以内的其他船舶，并将这些船舶的位置信息发送给船舶A的北斗系统；船舶A选择要通信的目标船舶B，并调整天线使天线指向船舶B，船舶A通过北斗系统将链接船舶B的请求及其自身的位置信息发送给北斗地面数据中心，北斗地面数据中心会将这些信息转发给船舶B；船舶B调整天线使天线指向船舶A，船舶A和船舶B通过微波系统进行链接，进行定向微波信号实时传输。 【EN】The invention discloses a method for realizing marine microwave directional communication based on a Beidou system.A Beidou system and a microwave system are arranged on ships, and each ship regularly returns the position of each ship to a terrestrial Beidou data center through the Beidou system; the ship A sends a link request to a Beidou ground data center by using a short message function of a Beidou system; the Beidou ground data center finds out other ships within the directional microwave communication range of the ship A and sends the position information of the ships to a Beidou system of the ship A; the ship A selects a target ship B to be communicated, the antenna is adjusted to enable the antenna to point to the ship B, the ship A sends a request for linking the ship B and position information of the ship A to a Beidou ground data center through a Beidou system, and the Beidou ground data center forwards the information to the ship B; and adjusting the antenna by the ship B to enable the antenna to point to the ship A, and linking the ship A and the ship B through a microwave system to perform directional microwave signal real-time transmission.
