摘　　要：提出了一种新的自适应波束形成技术——基于分数低阶矩的自适应波束形成算法。该算法充分利用对称稳定过程的特点,对冲击噪声和干扰有较强的抑制作用,弥补了传统的基于二阶统计量的自适应波束形成器不能应用于冲击噪声和干扰环境的不足。计算机仿真验证了该算法的可行性和有效性。This paper proposes a novel adaptive beamforming technique-fractional lower-order moment-based adaptive beam-forming algorithm. This algorithm exploits the characteristics of symmetric alpha stable (SaS) process fully and efficiently. The presented method is robust against additive impulsive noise and interference and overcomes the shortcoming of the traditional beamforrm-ing techniques , employing the second-order moments which can not be applied to impulsive noise and interference environments. The simulation results show the feasibility and effectiveness of the algorithm.
