The pulse transit time is an important factor that can be used to estimate the blood pressure indirectly. In many studies, pressures in the artery near and far from the heart are measured or the electrocardiogram and photoplethysmography are used to calculate the pulse transit time. In other words, the so-called contact measurements have been mainly used in these studies. In this paper, a new method based on radar technology to measure the pulse transit time in a non-contact manner is proposed. Radar pulses were simultaneously emitt
