Abstract
A self-modulating, remote, moving target detector for intrusion alarms, vehicle detection, and remote speed and distance measurement that includes a remote continuous wave radar transceiver that is used to detect moving targets. The same frequency used for the radar transmission is modulated in a continuous manner in order to transmit radar data concerning a moving target to a remote location away from the radar transceiver. The transceiver oscillator is self-modulated by the reflected signal received from a moving target in the transceiver and retransmitted such that the primary radar signal becomes the information carrier concerning the moving target, which is received remotely, in order to activate an alarm or a display system showing the moving target. The system could be utilized with any frequency from audio to light, with RF and microwave of primary interest.
