| 摘 要： | 研究了Ku波段降雨引起的交叉极化产生机理与影响。根据ITU-R交叉极化衰减预报预报模式,利用134°E亚太6号Ku波段卫星参数,结合广州、南京、长春、西安等城市的降雨数据对12 GHz频率上进行极化衰减量的分析计算。同时为补偿交叉极化引起的衰减,提出了两种极化补偿网络,效果明显。

| Abstract: | The mechanism and effects of cross-polarization induced by rainfall in the Ku-waveband is discussed.Based on the ITU-R prediction model and parameters of the Ap-6,134 ＆deg;E,Ku-waveband satellite,the cross-polarization attenuation quantity is calculated at 12 GHz with the rainfall data of Guangzhou,Nanjing,Changchun,and Xi＇an.In order to compensate for the attenuation caused by cross-polarization,two polarization compensation networks are put forward with desirable effect. |
