We describe how the phase reference of a circular array can be relocated from its center to an arbitrary radiating element located on the array while preserving the ability to project a collimated beam that can be steered into any azimuthal direction as with a conventional circular array. The ability to arbitrarily reposition the phase reference of the array makes this suitable for reducing Doppler effects when the array is in motion.
