摘要 在分析传统广义旁瓣相消器(GSC)自适应波束形成的基础上,提出一种改进的广义旁瓣相消器的波束形成方法,即基于特征结构的GSC波束形成算法(ED-GSC),该算法在投影特征空间中引入了期望信号方向矢量,能在期望信号功率较大时保持自适应波束形成方法性能,又能在期望信号功率较小时(甚至为零)具有较好的波束保形能力,对噪声有很好的鲁棒性。仿真结果表明:ES-GSC算法在高、中、低的信噪比下都具有较好的波束形成性能,是一种性能优越的波束形成算法。 The generalized side-lobe cancellation beam-forming based on the eigen-struture was proposed to overcome the disadvantage of the traditional GSC beam-forming. Simulation results reveal that this algorithm has the better beam-forming perfomance than conventional adaptive beam- forming algorithm in the lower, middle and high signal-noise-ratio (SNR), and it has robust characteristic and the better perfomance.
