摘要
船载卫星通信三轴天线采用三轴稳定两轴跟踪体制,分析了船载卫星通信三轴天线跟踪线极化星时产生反极化干扰的原因,对跟踪过程中极化不匹配对通信质量和跟踪性能造成的影响进行了分析,提出了三轴天线反极化干扰的解决方案。理论分析和实际验证表明,该方案能够消除由于极化不匹配产生的反极化载波干扰,提高了三轴天线跟踪和通信的稳定性和可靠性。
The shipboard three-axis antenna of satellite communication adopts three-axis stabilization and two-axis tracking mode. The reason of opposite polarization interference when using shipboard satellite communication three-axis antenna to track the line polarization satellite is analyzed. The impact of unmatched polarization on communication quality and tracking performance during tracking is also analyzed and a solution is proposed to solve the opposite polarization interference for three-axis antenna. The theory analysis and experiment prove that the scheme is able to eliminate the opposite polarization interference and increase the stabilization and reliability for tracking and communication of three-axis antenna.
