摘　　要：本文针对基于最小均方误差准则的自适应天线阵方向图的控零技术进行研究。首先介绍了最小均方误差准则的基本理论,然后对基于该准则的自适应天线阵进行理论分析,最后对需要信号和干扰信号的到达方向发生改变以及干扰信号的幅值发生改变的两种情况阵的抗干扰性能。Based on the minimum mean square error rule （MMSE）,the null control method of the adaptive antenna array is presented. This paper introduced the basic theory of MMSE,analysed the adaptive antenna array theory based on MMSE.Through modeling the receiving signal and interference signal with diferent amplitudes and directions of arrival （DOA）,the pattern and adaptive weighting vector of the adaptive antenna array are presented.The anti--interference performance of the adaptive antenna array is demonstrated by comparing the simulation results in different conditions.
