摘　　要：针对常规的自适应波束形成算法当训练数据中包含目标信号时,存在目标相消的问题,本文提出了一种基于双约束的稳健自适应波束形成算法,该方法不仅约束了目标方向的最小增益,同时也约束了权矢量的最大均方值。仿真分析表明,本文所提的方法不仅能够避免信号相消的现象,同时当存在导向矢量误差和少的训练数据的情况下也仍然有效,非常适合于用作工程领域。When traditional adaptive beamforming algorithm is used,target signal included in training data may be cancelled.A robust adaptive beamforming algorithm based on two-constraint is proposed,the minimum gain in target direction and the maximum mean squared of weight vector can be constrained simultaneously.Simulation result shows that the algorithm can not only prevent signal cancellation when target signal is contained in beamforming training data,but can also be effective when small steering vector errors is exist and amount of training data is limited;it is applicable in practical engineering.
