摘要
常规的自适应波束形成方法,在存在指向误差的时候性能严重下降,不能有效地抑制运动的干扰。针对这一现象,提出一种稳健的波束形成方法,在对实际导向矢量进行估计的同时,利用锥消矩阵对零陷阵进行加宽,能够对抗动干扰及指向误差。计算机仿真验证了该方法的有效性和正确性。
The performance of the traditional adaptive array algorithm is known to degrade in the presence of steering vector errors and therefore can not suppress moving jammers efficiently. A novel robust adaptive beam forming method is proposed in this paper. The beam is formed by two steps, estimating the actual steering vector firstly and widening the nulls using taper matrix. It is robust in countermining moving jammers and steering vectors errors. Computer simulations demonstrate the effectiveness and validity of the proposed algorithm.
