Abstract :
We propose a two frequency radar sensor structure for non-contact vital signs monitor. The vital signs measured by traditional Doppler sensor are diminished if the body has a large motion. The radar structure is proposed which is strong to human motions. This utilized frequency dependent dielectric characteristics of human body tissues.
