Abstract
In the area of pattern array synthesis, highly-directional radiation pattern guarantees accuracy and resolution, [1], which are accompanied by a drastic reduction in SLL. Pattern synthesis techniques are characterized by the two distinct scenarios; (1) the design of antenna array geometries for steering beampattern in an arbitrary direction in the space, and (2) the implementation of beamforming techniques for steering beampattern in the direction of interest in the space. This study has a major contribution for fully evaluating the performance of implementing the minimum variance distortionless response (MVDR) beamformer for the circular antenna array geometry in comparison with the different linear array geometries. A full and quantitative comparison between the circular antenna array and the different available linear antenna array geometries have been rigorously fulfilled for highlighting differences and advantages of the performance of the circular antenna array geometry over the different linear array antenna geometries using the four following concepts of (1) spatial correlation function (SCF), (2) antenna efficiency, (3) signal to interference ratio (SIR), and (4) propagation time delay.
