ABSTRACT:
1. An oscillator-detector circuit comprising operating potential energy rces, first self pulsing circuit means intermittently oscillatory for developing high frequency electromagnetic energy pulses of a preselected carrier frequency and repetition rate, electromagnetic energy radiating means electrically coupled to said first circuit for effecting radiation of said developed pulses into space and for receiving any reflected electromagnetic pulses, and a second oscillatory circuit means inductively coupled to said first circuit means and being rendered intermittently oscillatory during the occurrence of said developed pulses for selectively detecting variations in the magnitudes of said developed pulses caused by said reflected pulses and for developing an output signal having a frequency correlative to said variations, said first and second oscillatory circuits being parallel connected across said energy sources.
