“…Additionally, the Purina fractal's structural sparseness combines a significant aperture and therefore resolution while avoiding spatial aliasing as long as at least some sensors are sufficiently closely located [3][4][5][6], thus offering advantages that otherwise have to be achieved through thinning of arrays [7,8].…”

Abstract. Fractals have been proven as potential candidates for satellite flying formations, where its different elements represent a thinned array. The distributed and low power nature of the nodes in this network motivates distributed processing when using such an array as a beamformer. This paper proposes such initial idea, and demonstrates that benefits such as strictly limited local processing capability independent of the array's dimension and local calibration can be bought at the expense of a slightly increased overall cost.
