Microwave direction of travel detector by parallel sampling |
摘要 |
A microwave direction of travel detector and method of detecting the direction of an intruder in a protected region. The microwave direction of travel detector transmits and receives, by a microwave transceiver a microwave signal directed toward a protected area. The microwave return signal is modulated by a moving target to produce a Doppler signal. The received Doppler signal is amplified by a chain of amplifiers having two or more amplifiers coupled to the microwave transceiver. A controller monitors the output of each chain of the amplifiers. The microwave sensor is configured for parallel sampling an amplified Doppler signal output from each amplifiers having a low signal output and each successive chain of the amplifiers a successively higher signal output. The controller determines if there is a direction of travel motion from the intruder and sends an alarm.
