摘　　要：基于弹载智能天线系统对阵列接收信号的分析处理,运用空间谱估计理论,首先估计出信号源数与信号源角度信息。同时与载机加载目标信号源信息进行对比,分离出干扰源。最后将上述估计信息应用于波束控制理论中,实现天线阵列的主波束控制和方向图零点控制,使天线阵列真正实现智能接收的能力。Based on analyzing and processing receiving signal by smart antenna system in missile, the number and angle information of signal source were estimated by using spatial spectrum principle. Compared with the target information which was loaded on missile by plane, the source of interference was divided. The main-beam control and pattern null control can be realized by applying the estimation information to beam control theory. It was obvious that antenna array has function of intelligent receiving.
