Title: RADIO RANGING DEVICE

Abstract

A description is given of a super-regenerative oscillator ranging device provided with radiating and receiving means and being capable of indicating the occurrence of that distance between itself and a reflecting object which so phases the received echo of energy of a preceding emitted oscillation that the intervals between oscillations become uniform.

  • A super-generative radar system is described as having alternate phases of transmission and reception and is adapted to transmit for unequal durations in the absence of receiving energy and for equal and longer durations when energy of proper phase is received. (AEC)
  • A radio ranging device is described. It utilizes a super regenerative detector-oscillator in which echoes of transmitted pulses are received in proper phase to reduce noise energy at a selected range and also at multiples of the selected range.

  • An apparatus is described which senses the location of a vehicle with respect to another body and initiates a control signal at a predetermined distance from the body. A superregenerative oscillator circuit is arranged to have alternate transmitting and sensing phases of operation, controlled by a modulator which generates two unidirectional pulses adjustably spaced in time. The oscillator energy is transmitted to an antenna and the echo energy is sampled by the oscillator during its receiving phase producing a control signal when the echo energy is returned at the time the oscillator is in the receiving phase. A rectifier ismore » coupled to the super-regenerative circuit through a gate circuit, and means is provided for opening the gate circuit during the time the oscillator circuit is in the transmitting phase of operation. The rectifier therefore passes a unidirectional signal in response only to the sensing phases of operation.« less
