技術說明

一種多目標生理徵象偵測器包含一自我注入鎖定振盪器、一測距雷達、一頻率解調單元及一多目標生理徵象處理單元，該測距雷達接收該自我注入鎖定振盪器之該振盪訊號，且該測距雷達用以對一區域進行偵測並產生一注入訊號，該注入訊號注入該自我注入鎖定振盪器，使其處於自我入鎖定狀態，最後透過該頻率解調單元及該多目標生理徵象處理單元即可由該振盪訊號中取得生物體的距離與生理徵象資訊，本發明藉由該自我注入鎖定振盪器可讓測距雷達的敏感度大幅提昇，而能同時偵測不同距離下之生物體的生理徵象。 A multi-target vital sign detector includes a self-injection-locked oscillator, a ranging radar, a frequency demodulator and a multi-target vital sign processor. The ranging radar receives an oscillation signal of the self-injection-locked oscillator, detects an area and produces an injection signal. The injection signal is injected into the self-injection-locked oscillator to make it operate in a self-injection-locked state. The frequency demodulator and the multi-target vital sign processor are used to extract the distance and vital sign information from the oscillation signal of the self-injection-locked oscillator. In the present invention, the sensitivity of the ranging radar is greatly improved by the self-injection-locked oscillator so as to detect the vital signs of multiple biological objects at different distances from the multi-target vital sign detector.
