Abstract
A system for providing the plural variable phase RF signals required to control the beam pointing angle of a phased array. A light energy source (shown as a laser generator) is modulated by an RF signal and fed to a plurality of channels in parallel. Each of the said channels corresponds to one radiating element of the phased array and each channel includes as many selectively employed fiber optic delay lines of different lengths as are required to generate the discrete phases required at the corresponding antenna (radiator) element of the array. A commutating programmer controls the selection of individual radiating element phases for each successive beam pointing position.
