Abstract
A broadband detection performance of a circular microphone array has been degenerated by discrete noise interference. In this paper, a circular microphone array optimum design approach is proposed for discrete noise suppression in acoustic detection in the air. This approach utilizes the noise information of acoustic propagation's transfer function to mitigate its effect on broadband microphone array detection processing. It is demonstrated to be feasible to improve passive broadband detection ability of the circular microphone array through the adjustment of array shading weights. This is accomplished by numerically maximizing the deflection coefficient under the assumption of a small signal-to-noise ratio. Under this approach, the conventional beamformer is not redesigned, and only the shading weights of the conventional beamformer are adjusted.
