Webponents in a microphone array system is the so-called beamforming, which aims at recovering a desired signal from noisy observations with a spatial filter [12–15]. Circular arrays have drawn a signifi-cant amount of attention since, thanks to their symmetries, they can have a similar performance in different steering directions [16–18].
