摘要
提出了利用多次幅度测量实现多组阵列天线相位校准的方法,解决了多组阵列在天线辐射方向需要同相位合成的难题,保证了多组阵列实现高效率合成。介绍了校准方法的工作原理,给出了多组阵列天线进行相位校准的工作过程。对校准前后的天线测试结果进行对比分析,得出校准精度符合工程设计要求,且无需调试,易于实现远场自动校准,适用于多组阵列天线研制过程中的相位校准工作。
A method of adjusting phases of multi-array antenna by repetitious amplitude measurement is proposed. Also,radiation patterns of multi-array antennas with same phase incorporating is resolved,so as to conduce the incorporating of multi-array antennas with high efficiency.The theory of adjusting method is introduced,and then an example of adjusting phases of multi-array antennas is proposed to illustrate the process. By analyzing measurement results of adjusted antennas between unadjusted antennas,the adjusting precision could accord with demand of the project design.Also,this method is convenient to implementauto-adjusting,without debugging.Hence,it can be applied to phases adjusting in the multi-array antenna design.
