摘要
基于特征空间波束形成算法(ESB)是常用的一种自适应波束形成算法,已提出的ESB算法大多假设期望信号方向精确已知。本文在期望信号方向未知情况下,提出了一种基于子空间的波束形成方法。计算机仿真结果验证了该算法的有效性。
The eigenspace- based beamforming （ESB） algorithm is a commonly used adaptive beamforming algorithm and most ESB methods available in published literature have been designed under the assumption that the direction of the desired signal can be known exactly. In this paper, a method based on sub - space is presented to achieve beamforming when the direction unknown. The validity of the proposed method is confirmed by computer simulation.
