| 摘 要： | 目标信号和雷达天线之间的极化失配,导致接收机输出的误差信号电压中除基波正规分量外,还包含基波交叉分量和二次谐波分量等,降低了测角精度。通过对线极化目标信号和椭圆极化雷达天线匹配情况的分析和计算,获得了有关的公式和曲线。还对椭圆极化目标信号和椭圆极化雷达天线情况作了阐述。公式和曲线可作为选定卫星天线或地面站雷达天线椭圆极化率的参考依据。

| Abstract: | The polarization mismatch between the beacon signal and radar antenna leads to that, in the error signal voltage of the receiver output, besides the fundamental normal component, there exist fundamental cross component, second harmonics, etc., and then lowers the angular tracking accuracy. By analyzing the case linearly-polarized beacon signal and elliptically-polarized radar antenna, the related formulas and curves are given. The case elliptically-polarized beacon signal and elliptically-polarized radar antenna is also illustrated. Formulas and curves may be used as a reference for determination of the polarization ellipticity of the satellite antenna or Earth station radar antenna. |
