A non-contact pulse transit time measurement system utilizes two continuous-wave radars to measure the displacement waveforms at two positions on a human subject, and further computes the pulse transit time between these two positions of the human subject. Because the two continuous-wave radars make no metallic contact with the human subject, the measurement of the pulse transit time can be done more conveniently and comfortably.一種非接觸式脈搏傳輸時間量測系統藉由兩個連續波雷達偵測一人體上兩個位置的位移波形，進而計算該人體上該兩個位置之間的脈搏傳輸時間，由於該兩個連續波雷達皆為非接觸式量測方式，使得脈搏傳輸時間的量測更具便利性與舒適性
