摘　　要：文章在庞加莱球上研究了正交极化频率复用星地数据传输通道的极化损失和干扰问题。分析表明,极化损失和交叉极化鉴别率取决于接收天线和输入电磁波的极化轴比。同时,建立了极化损失和交叉极化鉴别率模型。The polarization loss and interference of the orthogonal polarization frequency re-use satellite-to-earth data transmission channels are studied on the Poincare sphere. Analysis shows that the co-polarization attenuation and the cross- polarization discrimination are dependent on the axial ratios of the receiving antenna and incoming electromagnetic wave. A co-polarization attenuation model and a cross-polarization discrimination model are set up.
