技術說明

本發明目的為同時偵測遮蔽物後受測者之距離資訊與生理資訊，以判別靜態人體與其他靜止物體之區別。其原理是以壓控振盪器之自我注入鎖定現象偵測自我注入鎖定路徑延遲並進而判斷感測範圍內本電路與不同物體之距離資訊。此外，路徑中受測者之心跳與呼吸等生理現象對無線電波造成之擾動，並對本電路進行頻率調變。相較於連續波雷達及頻率連續調制雷達，本發明使用自我注入鎖定技術可同時提供距離資訊與生理資訊，且具備較高的靈敏度。 This invention can simultaneously measure the range and physiological information of the subject behind a shelter, in order to distinguish the static individual and other stationary objects. The principle is applying the self-injection-locking pheomenon of the voltage-controlled oscillator to detect the path delay and judge the range information of this invention and various objects during the sensing range. Moreover, the subject's vital signs such as heartbeat and breath would disturb the radio wave, and frequency-modulate this circuit. Compared to continuous-wave radar and frequency-modulated continuous-wave radar, this invention utilizes self-injection-locking technique to provide range and physiological information at the same time, and has higher sensitivity.
