Receiving antenna system

Abstract

Abstract MEANS CONNECTING EACH OF SAID ENERGY PICK-UP MEANS TO A SECOND INPUT OF THE HETERODYNE MIXER ASSOCIATED WITH THE CORRESPONDING ONE OF SAID INDIVIDUAL RECEIVING ELEMENTS, A PLURALITY OF FEED HORNS DISTRIBUTED OVER A HEMISPHERICAL AREA OF SAID LENS, A PHASING OSCILLATOR, SWITCHING MEANS CONTROLLABLE TO CONNECT SAID PHASING OSCILLATOR TO SAID ENERGY FEED HORNS ONE AT A TIME IN A SELECTED SEQUENCE, THE RATIO OF THE DIAMETER OF SAID LUNEBERG LENS TO THE DIAMETER OF SAID SPHERICAL ARRAY BEING EQUAL TO THE RATIO OF THE FREQUENCY OF THE SIGNAL SUPPLIED BY SAID INDIVIDUAL RECEIVING ELEMENT TO THE FREQUENCY OF THE SIGNAL SUPPLIED BY SAID PHASING OSCILLATOR, AND MEANS FOR COMBINING THE OUTPUT SIGNALS OF SAID HETERODYNE MIXERS. 9. A RECEIVING ANTENNA SYSTEM COMPRISING A PLURALITY OF INDIVIDUAL RECEIVING ELEMENTS DISTRIBUTED IN A SPHERICAL ARRAY, A LIKE PLURALITY OF HETERODYNE MIXERS, A PLURALITY OF PARAMETRIC AMPLIFIERS, EACH OF SAID PARAMETRIC AMPLIFIERS COUPLING ONE OF SAID INDIVIDUAL RECEIVING ELEMENTS TO A FIRST INPUT OF A CORRESPONDING ONE OF SAID HETERODYNE MIXERS, EACH OF SAID PARAMETRIC AMPLIFIERS BEING ADAPTED TO OPERATE IN THE LOWER-SIDEBAND, UP-CONVERSION MODE, A PUMP SIGNAL GENERATOR, MEANS COUPLING SAID PUMP SIGNAL GENERATOR TO EACH OF SAID PARAMETRIC AMPLIFIERS, SAID LAST-MENTIONED COUPLING MEANS PROVIDING THE SAME RELATIVE PHASE SHIFT BETWEEN SAID PUMP SIGNAL GENERATOR AND EACH SAID PARAMETRIC AMPLIFIERS, A SPHERICAL LUNEBERG LENS, A PLURALITY OF ENERGY PICK-UP MEANS DISTRIBUTED OVER THE SURFACE OF SAID LENS, THE DISTRIBUTION OF SAID PICK-UP MEANS ON SAID LENS CORRESPONDING TO THE DISTRIBUTION OF SAID INDIVIDUAL RECEIVING ELEMENTS ON SAID ARRAY,
