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。
Due to the influence of mutual coupling, the current distribution of each unit in the antenna array is different, therefore, the traditional synthesis method can not obtain a satisfactory pattern; and the matrix method of moment method requires a great amount of calculation for a large array, Limit its scope of application. In this paper, a method of synthesizing the dipole antenna array pattern is proposed, and several low sidelobe patterns are obtained. Due to the better handling of the effects of mutual coupling, this method greatly saves computational time and memory cells and provides a great deal of flexibility in the type of stimulus. The method in this paper is especially suitable for the large array of pattern synthesis.
