| 摘 要： | 利用船载惯性导航系统提供的姿态信息，建立了船载A-E-C三轴稳定卫星通信天线的坐标计算模型，利用该模型推导了横倾角和纵倾角的计算公式，以及海上动态条件下极化角实时修正公式，控制船载卫星通信天线隔离船摇。经过MATLAB仿真运算和数值分析验证，并应用于实际系统中，提高了船载卫星通信地球站天线的性能。该模型还为优化船载卫星通信天线的控制提供了数学分析工具。

| Abstract: | A coordinate computing model of A-E-C three-axis stabilized antenna for ship-borne satellite station is built by using the information provided by marine inertial navigation system. Based on this mod-el,the heel angle and the trim angel calculation formulas are derived,as well as the polarization angle ad-justment formulas in maritime dynamic conditions. After simulation and analysis in MATLAB and applica-tion in practical systems,this model proves to be able to enhance the performance of the ship-borne satel-lite station antenna. Furthermore,this model provides the numeric analysis approach for optimization of the ship-borne satellite station antenna control algorithm. |
