摘要
为克服动中通两轴稳定造成的极化失配问题,在对卫星天线波束特性和波束稳定实质进行分析的基础上,建立"动中通"卫星天线极化轴稳定的通用性模型。基于此模型对天线极化轴稳定性进行了仿真,定量地证明了极化轴稳定的必要性。最后根据所推模型给出了两种极化稳定方案。
For overcoming the polarimetric crossing as a result of the stabilization of antenna only on two axes in satellite communication in motion, a normal model of the stabilization of antenna polarization axis is established, based on analyzing the beam charactors of satellite antenna and stabilization of beam. The stabilization of antenna polarization axis is simulated based on the mobel,and the simulation results quantificationally prove that it is obligatory to stabilize the antenna polarization axis. Finally,two methods for the stabilization of antenna polarization axis are given based on the mobel.
