OMNI-DIRECTIONAL MICROWAVE DOPPLER SENSOR

摘要

The present invention relates to a doppler sensor comprising a signal oscillating unit for generating a signal for detecting the movement of a moving object; an antenna unit for transmitting the signal generated by the signal oscillating unit and for receiving a reflected signal; a signal combining unit for frequency-combining the received signal and the signal generated by the signal oscillating unit; and a signal amplifying unit for filtering a baseband signal output by being synthesized from the signal combining unit and for amplifying the filtered signal. The present invention is configured to be formed on a dielectric substrate of a single plane, thereby providing great mobility by being miniaturized and portable.
