A CDAA of which the Wullenweber is a type, consists of a group of omnidirectional antennas symmetrically spaced about the periphery of a circular reflector screen. The location of each antenna with respect to the screen and to the adjacent antenna is such that by using a suitable antenna output scanning system, the array provides high unidirectional gain in all directions of azimuth. The scanning procedure results in sweeping the horizon with a direction-finding beam through a continuous arc of 360 deg. A CDAA can also be connected to fixed-lobe-forming devices that provide fixed directional beams for receiving signals in any desired direction of azimuth. The array is capable of creating either a wide or narrow beam by selecting antennas in the array.
