| Abstract(in English) | This paper presents a microwave array radar system for monitoring and imaging human respiratory motion. We developed a 2.4-GHz nine-element array radar system and introduced a respiration-sensitive radar imaging algorithm that locates the body part undergoing respiratory motion and measures the respiratory rate. We adopted a beamformer-based radar imaging method using a bandpass filter matched to the respiratory frequency. The proposed system located the body part undergoing respiratory motion with an average error of 14.4 cm and measured the respiratory period with an average error of 0.65%. These results indicate that our array radar system is effective at monitoring sleeping people for respiratory disorders such as sleep apnea syndrome. |
