摘　　要：介绍了在信号来向和阵列流型未知情况下进行波束形成的常用方法,阐述了盲波束形成的恒模算法和高阶累积量算法。提出了基于独立分量分析的盲波束形成算法,结合目前阵列信号处理系统中的实际问题对基于恒模、高阶累积量和独立分量分析的盲波束形成算法进行了仿真比较。理论分析和仿真实验表明,基于独立分量分析的盲波束形成算法在强干扰信号、信号来向相近和收敛速度等方面性能优越。The common methods for blind beam-forming without knowing direction of arrival and array manifold are introduced,and the constant modulus algorithm and high order accumulation algorithm of blind beam-forming are illustrated.Blind beam-forming algorithm based on independent component analysis is proposed,and the three methods are simulated under the problems in actual beam-forming system.Theoretical analysis and numerical simulation reveal that the proposed blind beam-forming algorithm based on independent component analysis performs better in aspects of strong interference,close direction of arrival and convergence speed.
