摘要 提出了一种基于线性约束最小方差波束形成(LCMV)的自适应方向图控制方法。该方法通过在原有线性约束基础上构造新的线性约束,然后根据新组成的线性约束进行LCMV自适应波束形成,所得到的自适应方向图在固定零点方向和干扰方向形成零陷的同时保留了期望静态方向图的副瓣电平特性,从而能够减小快变干扰的影响,并且计算十分简便。计算机仿真证明了本文方法的有效性。 An adaptive pattern control method based on linearly constrained minimum variance（LCMV） is presented. A new linear constraint on the base of the former constraints is constructed, and then LCMV adaptive beamforming is used. The last adaptive pattern holds the expected sidelobe level characteristic well and forms nulls in the directions of the interferences and the constrained nulls at the same time. It can reduce the interference influence and computation load. Computer simulations show the validity of the approach.
