Blind Source Separation of Human Body Motion using Direct Conversion Doppler Radar

Direct conversion Doppler radar can provide remote non-invasive monitoring of cardio-pulmonary activity of human subjects. However, real world life signs monitoring requires real-time processing of data over long monitoring periods, during which it is unlikely that the subject can be expected to sup...

Description
Summary:Direct conversion Doppler radar can provide remote non-invasive monitoring of cardio-pulmonary activity of human subjects. However, real world life signs monitoring requires real-time processing of data over long monitoring periods, during which it is unlikely that the subject can be expected to suppress other body motion. Measurement of cardiopulmonary motion of a human subject with extraneous subject movement in the field of view of a Doppler radar system is a complex problem. The use of multiple antennas and blind source separation signal processing techniques is a logical approach for monitoring humans in real world conditions. Described here is the successful separation of cardiopulmonary motion and hand motion for a single subject.
