分数时延估计文档对于宽带信号, 基于移相的窄带波束形成方法会导致方向图波束指向的偏移和主波束畸变, 并且无法有效地抑制宽带干扰。该文提出了基于数字时延加抽头延迟线 (tapped delay line , TDL)结构的宽带自适应波束形成方法。 该方法采用数字时延滤波单元补偿宽带信号在波束指向上的相位和包络偏移, 并用基于TDL 的空时二维滤波处理抑制宽带干扰。分析和实验结果表明, 该方法可以有效地合成空间宽带波束并抑制宽带干扰, 提高信干噪比(sig nal-to-interference-plus-noise r atio , SINR)增益。(frac delay estimation)
