Low Discrepancy Sparse Phased Array Antennas [PDF]

open access: yesSensors, 2021
Sparse arrays have grating lobes in the far field pattern due to the large spacing of elements residing in a rectangular or triangular grid. Random element spacing removes the grating lobes but produces large variations in element density across the aperture. In fact, some areas are so dense that the elements overlap.
