| 摘 要： | 相控阵天线阵面的制造、安装产生结构误差，结构误差会导致天线电性能的下降，严重制约高性能相控阵天线的发展.因此，将阵面存在的结构误差作为附加的相位因子引入到天线方向图函数中，建立了平面六边形相控阵天线阵面结构误差与天线电性能之间的结构-电磁耦合模型，并分析了平面度和阵元安装精度与天线电性能的直接影响关系，给出了满足天线电性能要求时的阵面结构误差临界值，为工程设计人员制定天线加工公差提供参考.

| Abstract: | The electromagnetic performance of phased array antenna (PAA) is degraded because of the array plane structural error caused by manufacturing processing and assembly. It seriously restrict the realization of high performance of the phased array antenna. Therefore, by introducing the plane structural errors into the antenna pattern function as an additional phase factor, a coupled structural-electromagnetic model was developed, which described the effect on the performance of planar hexagonal phased array antenna with the plane structural errors. The direct influence relationship of the electromagnetic performances of antenna with the plane installation accuracy and planar tolerance was analyzed. The critical value of array plane structural error was given when meet antenna performance requirement. The analysis results provide a theoretical guidance for the engineer to set the tolerance in manufacturing antenna. |
