应用背景频率不变波束形成(Frequency-invariant beamforming, FIB)在麦克风阵列语音信号的无失真采集和处理中具有重要的应用。经典的FIB设计方法通常是在远场平面波的模型下提出的，本文根据麦克风阵列近场球面波模型，将空间响应变化函数(spatial response variation, SRV)运用到近场线性约束方差(Linear Constrained Minimum Variance, LCMV)宽带波束形成中，把空间响应函数作为优化条件，然后根据拉格朗日乘子法计算得到闭式解，从而得到频率不变的权向量。但是该方法受到环境干扰和噪声影响，权值分配值需要较大的浮动。因此本文采取了自适应加权频率不变波速形成，能够根据环境自适应的选择加权值的大小。仿真实例证明了所提方法的有效性和理论分析的正确性。关键技术The frequency invariant beamforming (FIB) has important applications in the microphone array speech signal acquisition and processing.
