On the Design of 3D Steerable Beamformers With Uniform Concentric Circular Microphone Arrays
TL;DR: In this article, a beamforming method is developed in which the beamformer's coefficients are identified by solving a linear system of equations formed by approximating the $N$ th-order optimal target beampattern with the beam-former's beamp attern while the resulting beAMPattern can be steered flexibly in the 3D space.
