Abstract	Concentric ring arrays can provide effective beamforming and achieve frequency invariant beampatterns. For long range signal acquisition, the array has a large number of array elements, and partial adaptation is often necessary to increase tracking ability and reduce computation. The topic of this paper is the study of a partially adaptive concentric ring array for three-dimensional audio signal acquisition. We develop the partially adaptive array through partition matrix formulation, provide the associated adaptive structure, and derive the steady state residual interference and noise power that can serve as a criterion to evaluate different partition structures. A comparison of several partition schemes using the criterion is given, and the theoretical results are supported by simulations.
