Doppler radar for sleep medicine

A design for a physiological radar monitoring system (PRMS) is presented that can be integrated with clinical sleep monitoring systems. The PRMS uses two radar systems at 2.45 GHz and 24 GHz to achieve both high sensitivity and high resolution. The system can acquire data, perform digital processing and output appropriate conventional analog outputs, which can be read and interpreted in a standard sleep monitoring system. The PRMS system was tested on ten patients and the results compared favorably with a gold standard monitoring system. The results show the possibility of integrating a PRMS with a standard monitoring system to achieve more informative results.
