| 摘 要： | 分析阵面变形误差对有源相控阵天线(active phased array antenna, APAA)电性能的影响，对研究和发展高性能APAA非常重要。将阵面随机误差和阵面变形作为附加的相位因子引入到天线方向图函数中，建立了平面矩形APAA的阵面变形误差与电性能之间的结构〖CD*2〗电磁耦合模型，并仿真分析了阵面存在变形误差时的天线远场方向图。通过所提方法与结论，工程设计人员可对加工公差提出更合理的要求。

| Abstract: | The analysis of the influence of the distorted plane on the electromagnetic performance of the active phased array antenna (APAA) is of great significance to the research and development of the high-performance APAA. By introducing the plane random errors and deformations into the antenna pattern function as an additional phase factor, the coupled structural electromagnetic model is established of the relationship between the distorted plane and the electromagnetic performance of the planar rectangular APAA. The far field pattern of antenna with the deformation of array plane is studied by simulation. By the proposed method and conclusion, the antenna designers may set reasonable requirement on the tolerance in manufacturing antenna. |
