| 为解决共形相控阵天线因阵元间极化相位差异使其难以同相合成的问题，基于接收天线理论对天线的极化相位进行了分析。提出了一种天线极化相位补偿方法，根据天线电磁矢量旋转角度来补偿极化相位，实现了对任意波束指向下天线极化相位的快速实时补偿。分别使用极化修正相位和远场校准后的相位进行测试，在波束指向方向的增益误差小于0.2 dB，验证了方法的有效性。该方法可以广泛应用于测控、通信、雷达等领域的各类共形相控阵天线中。 |

| Abstract: |
| To solve the problem that in-phase synthesis of conformal phased array antennas is difficult due to the polarization phase difference between array elements,the polarization phase of the antenna is analyzed according to the receiving antenna theory.A method for compensating antenna polarization phase is proposed,which compensates for polarization phase according to the rotation angle of the antenna electromagnetic vector,achieving fast and real-time compensation of antenna polarization phase under any beam direction.The polarization compensation phase value and the far-field calibrated phase value are used for testing,and the gain error in the direction of beam pointing is less than 0.2 dB,thus verifying the effectiveness of the method.This method can be widely applied in various conformal phased array antennas in fields such as tracking,telemetry,and command(TT&C),communication and radar. |
