Circularly symmetric and zero reduudancy planar array having broad frequency range applications

A planar array type, having a source location, source imaging or target illumination in the projection beam for other applications a wide frequency range. The array is circularly symmetric non-redundant by a plurality of sensing or transmitting units, these units may be arranged substantially eliminate grating lobes over a broad frequency range. Each unit receives a signal transmitted to or from each unit are appropriately phased to control the beam array.
