Research on Phase Array Antenna Beam Switch Algorithm Applied in Synchronous Satellite Communication

提出了一种基于"地球系—地理系—载体系"的三坐标转换算法,解决了相控阵天线实时波束切换的需求,实现了搭载该相控阵天线的无人飞行器可在任意位置和任意姿态角与同步卫星进行不间断通信。通过数值模拟,证明该算法基本满足设计需求,具有一定的实际应用价值。

Propose the algorithm base on three coordinate transformations with earth-geography-basement to solve the demand of real-time beam switching of phase array antenna. With the algorithm, the uninterrupted communication between synchronous satellite and UAV with arbitrary position and attitude is implemented. The numerical simulation is presented and prove that the algorithm is useful and valuable in practical application.
