摘要
由于互耦的影响,天线阵中各单元的电流分布各不相同,因此,传统的综合方法不能得到满意的方向图;而矩量法综合阵方向图时对大阵需要极大的计算量,限制了它的适用范围。本文提出了一种综合偶极子天线阵方向图的方法,并用它得到了几个低副瓣方向图。由于较好地处理了互耦的影响,这种方法极大地节省了计算时间和存贮单元,并使激励源型式具有很大的灵活性。本文的方法特别适用于大阵的方向图综合。
The mutual coupling between elements in arrays makes the current distribution on elements different from each other and the classical method of synthesis can not give out a precise pattern. On the other hand, the moment method is confined to small arrays by the computer capacity. In this paper a new method for synthesizing an array consisting of parallel dipoles is described and some applications to low-sidelobe pattern synthesis are presented. Properly dealing with mutual coupling, the method decreases the computation time and the need of memory capacity greatly. It can be applied to any excitation sources, and particularly to large arrays.
