Abstract :
Uniform circular arrays (UCAs) are naturally suited to provide 360 degrees of coverage in the azimuthal plane. In this paper, we describe a new approach for synthesizing array patterns with guaranteed maximum sidelobe levels for any look direction. The advantage of this approach is that it is computationally efficient which makes it eminently suitable for real-time beamforming and beamsteering applications. The approach is based on the Dolph-Chebyshev method for uniform linear arrays except here, the Dolph-Chebyshev method is applied to the transformed array response vector of the UCAs
