A geometrically simple circular array topology for two dimensional (2D) sparse multiple-input-multiple-output (MIMO) array is proposed. The focusing and imaging properties of the array in the millimeter-wave range with narrow-bandwidth are studied by simulation. The results for the focusing property show that the array has decent sidelobe levels over a wide field of view within near and far field. Imaging capability of the array presents that point-like targets are well reconstructed with a high dynamic range.
