| description | An intrusion detection apparatus including a sensor for sensing an objectionable interference phenomenon within a detection area and developing a pulse train coincident therewith, signal processing circuitry responsive to the pulse train and operation to actuate a Gunn diode microwave generator or the like in a pulsed manner causing it to transmit microwave energy into the detection area in synchronism with the interference phenomenon, a microwave receiver for detecting microwave energy reflected from the detection area and for developing detection signals indicating motion within the monitored area, and further signal processing circuitry responsive to the detection signal and operative to actuate an alarm or the like. |
