摘要

由于实际应用中可能存在移动源，因此设计具有可操纵通带的宽带波束形成器用于麦克风阵列具有重要意义。本文提出了一种基于Farrow结构、对传声器失配具有鲁棒性的可调频不变(SFI)宽带波束形成器的设计方法。该方法具有封闭解，具有较低的计算复杂度。几个设计实例表明，该方法在保持频率不变通带方面优于现有的同类方法。

Design of steerable and frequency invariant beamformers robust against microphone mismatches

Due to the presence of possibly moving sources in practical applications, it is of interest to design wideband beamformers with a steerable passband for microphone arrays. In this paper, the design approach of steerable and frequency invariant (SFI) wideband beamformers is presented, which is based on the Farrow structure and robust against microphone mismatches. The proposed method has a closed-form solution, thus has a lower computational complexity. Several design examples are presented to show the superior performance of the method over its existing counterpart in keeping a frequency invariant passband.
