摘要
文章提出了宽带自适应波束形成及稳健设计方法,建立了二次约束宽带波束形成稳健设计模型,从理论上解决了自适应阵观察方向的稳健设计问题,彻底抛弃了自适应阵需要时延补偿的环节。所建立的阵处理器能抵消40dB以上的干扰,工作带宽达到两个倍频程,在理论上为被动跟踪系统设计最佳宽带接收阵和阵处理器作了准备。
An adaptive broadband beamforming method and a robust design technique are presented in this paper. The model of broadband beamforming with quadratic constraint is established and, in theory, robustness of the beamformer in searching direction is achieved. Delay compensation is not needed, and interference is canceled up to more than 40dB within two octave-bands.
