Abstract:
Medical monitoring has improved over the last four decades to include increasingly less invasive techniques. In particular, Doppler radar methods are emerging as a means for remote sensing of respiration and heart activity, which until recently was restricted to science fiction. The potential for such nonintrusive accrual of biomedical data applies to a wide range of health/life monitoring applications and has motivated the development of a wealth of radio and signal processing research. Notably, there has been keen interest in addressing the challenge of simultaneously monitoring cardiopulmonary signs for multiple subjects in close proximity.
