Through-wall UWB radar operating within FCC's mask for sensing heart beat and breathing rate

Non-invasive sensing of heart beat and breathing rate using UWB radar within the FCC's mask between 3.1 to 10.6 GHz and operating within -41 dbm/MHz has been developed. Compared to existing radars, the EIRP of UWB is much lower and it can also achieve comparable performance with the unique capability of through the wall environment. The UWB radar transceiver system architecture is presented and the results in monitoring breathing rate and heart beat of the human object will be discussed.
