| 摘 要： | 提出了在基于来波方向估计和自适应波束成形的相控阵天线系统中,用多重信号分类(MUSIC)算法实现来波方向估计,并使用线性约束最小方差(LCMV)的自适应算法控制天线的主瓣方向,实现对期望信号的跟踪,同时实现对干扰信号的零陷处理。仿真结果表明,MUSIC算法可以有效识别相控阵天线接收端的信号的入射方向,LCMV算法可以实现对有用信号的自适应跟踪和对干扰信号的抑制。

| Abstract: | This paper presents an adaptive beamforming system based on estimating of direction of arrival (DOA) and then steering main-beam automated for phased array antenna.The system uses MUSIC to compute the DOA and uses LCMV to control the direction of signal of interest and null the interference signal.Simulation results show that MUSIC can identify the direction of multiple signals accurately,and LCMV can implement adaptive tracking and steering for the interested beam,and suppress the uninterested signal. |
