Ultra-wideband Radar Detection of Breathing Rate: A Comparative Evaluation
… explores the use of a commodity ultra-wideband (UWB) radar based device to detect breathing rate for health monitoring applications. Health monitoring devices observe physiological signals to detect medical conditions. We focus on capturing the small mechanical movements caused by breathing. This …

Remote cardiac monitoring using radar
… order to study this problem, an ultra wide band (UWB) pulse radar and a fixed-frequency amplitude based radar were constructed and evaluated. The UWB radar was not reliable and did not produce repeatable results, but the fixed-frequency radar successfully recorded heartbeat signatures from twelve …
