摘　　要：为了得到一种简单有效的阵列天线方向图控制方法,首先,从二元阵天线的结构及方向图入手,结合方向图乘积定理,通过对阵元天线激励幅度和相位的控制,得出了一种基于二元阵交替激励的阵列天线方向图调控方法;然后,结合理论推导,对真实的阵列天线进行了激励控制实验,并对实验数据的分析,重点研究了阵列天线归一化方向图的变化,证实所研究方法的可行性。In order to get a simple and effective control method for array antenna pattern, according to the pattern multipli-cation theorem, concerning about the structure and pattern of binary antenna, with the control of amplitude and phase of the antenna units, a kind of array antenna pattern control method based on alternating excitation of binary antenna was come up with. Combining theoretical analysis and analysis of data from the array antenna excitation control experiment, fo-cused on the changes of array antenna normalized pattern, the feasibility of this method was confirmed.
