Abstract

<p>Chronic obstructive pulmonary disease (COPD) results from smoking habits and air pollution escalation in developing countries and. A clinical COPD screening adopts a spirometer with mouthpiece, which requires medical personal we developed a COPD screening system which conducts non-contact screening without the help of medical personal. The proposed system consists of dual doppler radars (10mW, 24 GHz). The examinees front side Doppler radar in sitting position captures thoracic movements using arctangent remodulation.of I and Q outputs a Doppler radar.. The combination of front side and back side Doppler radars cancel to-and-fro body movements. we tested the proposed system for five healthy subjects and five pseudo COPD subjects (narrow straw attached to spirometer mouthpiece which simulates bronchial narrowing induced by COPD (5 males, average 23) . FEV1.0% (bronchial narrowing score signifivantly correlates with that derived by spirometer (r = 0.93), and sensitivity and specificity were 100% (threshold, FEV1.0%=70%).</p>
