| 摘要: |
| 针对卫星通信站接收交叉极化隔离度下降的问题，首先利用Matlab软件绘制了隔离度与
极化角、线圆转换器偏差的关系曲线，然后通过实测值和公式相比较，推导出偏差理论值。
最后，根据推导出的结论，通过工程实践解决了极化隔离度下降的问题，调整后测试的结果
也验证了该方法的可行性。 |

| Abstract: |
| For the problem of polarization isolation decreasing on Satellite Commun
ications Station,Matlab is used to protract the graph about isolation with
circularlinear switching and polarization angle.By comparison between measured
value
and expressions,excursion angle is derived. Finally,according to the conclusion,
the problem of polarization isolation decreasing is solved by project practice.
T
he test result validates the feasibility of the method. |
