Abstract

This paper investigates the use of a Purina fractal array for beamforming. We compare the performance of this array to full lattice arrays of same aperture and element count in terms of beam pattern and complexity. Further, the array's sensitivity to element displacement and failure is investigated. Simulations indicate that the Purina array can offer significant advantages over its benchmarkers particularly in the lower half of the spectrum.
