  • Patent number: 4866441
    Abstract: A microwave signal receiving apparatus comprises a delay line for distributing a microwave signal, samplers for sampling the signal spatially along the delay line and producing analog samples, analog-to-digital converters for converting the analog samples to digital samples, and digital memories associated with each converter for storing the digital samples.
    Type: Grant
    Filed: October 30, 1986
    Date of Patent: September 12, 1989
    Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of National Defence
    Inventors: Larry J. Conway, Paul I. Pulsifer, William D. Cornish
  • Patent number: 4757318
    Abstract: An RF signal receiving/transmitting apparatus for use with a phased array antenna having a plurality of antenna elements comprises a plurality of signal processing circuits, each circuit being connected to and associated with one of the antenna elements and including a signal distributing/combining device connected to its associated element, a plurality of sampling gates for spatially sampling a distributed signal or applying analog samples to the distributing/combining device, and analog-to-digital or digital-to-analog converters connected to an analyzer for analyzing/generating a plurality of digital samples which are received or to be transmitted by the antenna elements.

    Inventors: Paul I. Pulsifer, William D. Cornish, Larry J. Conway
  • Patent number: 4679168
    Abstract: This invention describes a system for digitally storing high-frequency signals with the ability to retrieve and transmit these stored signals repetitively or with various selectable delays. The invention provides means to store the radio frequency signal by sampling the voltage of the wave distributed along delay line means at a number of points in parallel. These voltages are then quantized and stored in a digital memory. The wave is reconstructed at the output by the reverse process.
