Abstract

A uniformly distributed random planar array is analyzed using a unified probabilistic approach. The expected beam pattern and maximum peaking sidelobe is derived in closed form considering an arrangement of randomly distributed elements within a uniform distribution that are confined to a square geometry. Theoretical and numerical beampatterns are compared to simulated and experimental results of a sixteen-element electrically large planar square aperture using microstrip patch antennas. Results are also compared to a theoretical maximum peaking sidelobe analysis.
