INTRUSION DETECTION APPARATUS HAVING SUPERVISORY CONTROL MEANS
The illustrated detection apparatus includes a radio frequency transmitter and a receiver having an amplifier which has a constant gain portion and a following roll-off above the highest motion Doppler frequency signal to be detected. The transmitter is a Clapp oscillator. A free running multi-vibra...

description | The illustrated detection apparatus includes a radio frequency transmitter and a receiver having an amplifier which has a constant gain portion and a following roll-off above the highest motion Doppler frequency signal to be detected. The transmitter is a Clapp oscillator. A free running multi-vibrator is coupled into a voltage regulator of the bias supply of the Clapp oscillator to superimpose a supervisory signal which falls within the roll-off portion. |
