  • Fiber optic data distribution for phased array antenna
    Patent number: 4583096
    Abstract: A fiber optic data distribution system is disclosed for distribution of the phase shift commands to an electronically steered antenna array. Novelties include the fan-out of a single bundle to multiple receptors, equalization of optical path for precise synchronization, the use of the RF active side of the antenna for data distribution, the use of the antenna radome as support structure for the fiber optics, and an optical reflector to divert light from the plane of the radome to the transmit/receive element.
    Type: Grant
    Filed: May 23, 1983
    Date of Patent: April 15, 1986
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventors: Brian M. Bellman, Ronald G. Kraus
  • Clock distribution circuit for active aperture antenna array
    Patent number: 4521893
    Abstract: A system for communicating a time reference or clock signal to a plurality of processors over substantial distances where propagation time between units is significant compared to the processing time. The timing signal is in the form of two continuous sinusoidal waves of different frequency but equal amplitude, which are added to give equal contributions in the resultant composite, two frequency, sum signal. The resulting waveform has sharply defined nulls occurring at the difference frequency which are used as a precise time reference.
