摘　　要：为了解决船载卫星通信天线跟踪精度低导致通信质量下降的问题,以船载卫星通信天线跟踪系统为基础,研究船载卫星通信天线跟踪误差自动补偿方法。船载卫星通信天线跟踪系统通过搜索阶段与跟踪阶段2个步骤跟踪船载卫星通信天线。根据船载卫星通信天线跟踪结果,采用相位补偿方法控制船载卫星通信天线运动中的指向误差,实现船载卫星通信天线跟踪误差自动补偿。实验结果表明,该方法可以实现船载卫星通信天线跟踪误差的自动补偿,具有较高的船载卫星通信天线跟踪精度,提升了船载卫星通信质量。In order to solve the problem that the low tracking accuracy of shipborne satellite communication antenna leads to the decline of communication quality,based on the shipborne satellite communication antenna tracking system,the automatic compensation method of shipborne satellite communication antenna tracking error is studied.The ship borne satellite communication antenna tracking system tracks the ship borne satellite communication antenna through two steps:search phase and tracking phase.According to the tracking results of shipborne satellite communication antenna,the phase compensation method is used to control the pointing error in the movement of shipborne satellite communication antenna,so as to realize the automatic compensation of tracking error of shipborne satellite communication antenna.The experimental results show that this method can realize the automatic compensation of tracking error of shipborne satellite communication antenna,has high tracking accuracy of shipborne satellite communication antenna,and improves the quality of shipborne satellite communication.
