Sidelobe behavior of hexagonal and circular arrays

The sidelobe behavior of circular and hexagonal arrays with uniform distributions are analyzed to identify comparisons in sidelobe level. Isotropic radiators are preferred since they provide relevant information on the fundamental beamforming behavior. The mathematical process required for this analysis includes a statistical formulation of the array factor, including the mean, or expected value. Numerical results are included to illustrate scanning from zenith to meridian elevation angles to evaluate the theory and compare the behavior of both circular and hexagonal arrays.
