ABSTRACT:
An apparatus and method for scanning a circular array through 360.degree. with tapered aperture illumination function to achieve radiated beams with desired sidelobe levels. A switching matrix selects a predetermined number of active elements from the total number of elements disposed about the circle to form a sub-array. To this sub-array a variable amplitude distribution network is coupled to establish excitations at each active element in accordance with a desired amplitude distribution function.
