| 摘 要： | 针对星载电子侦察阵列天线二维测向的应用背景,研究如何选取合适的圆形天线阵列方式以适应多倍频程信号的接收、处理。通过理论分析,给出了3种圆阵模型的阵因子表达式,并对其分别进行大量的最优搜索和计算。结果表明,带有中心阵元的外层阵元数为奇数的单层均匀圆阵是比较合理的选择。

| Abstract: | To implement two dimensional direction finding of emitters on the ground by antenna array in electronic reconnaissance satellites,the paper studies how to select a suitable circular array to receive multi-octave signal.Theoretically array factors for three circular array models are given.The optimal array parameters for three models are obtained by computer simulation.The comparison of array factor results for multi-octave signal shows that the uniform circular array with one antenna element in the center a... |
