L'importance des systèmes de surveillance respiratoire pendant le sommeil a augmenté en raison du diagnostic précoce du syndrome d'apnée du sommeil (SAS) à la maison. Cet article présente un système de surveillance respiratoire simple adapté à un usage domestique et doté de cibles en 3D. La résolution en distance et la résolution en azimut sont obtenues par un signal de transmission à fréquence échelonnée et des réseaux MIMO avec des codes de séquence M de paires préférées modulant doublement en transmission et en réception, respectivement. Grâce à l'utilisation de ces codes, les codes de séquence Gold correspondant à toutes les combinaisons d'antennes sont modulés de manière équivalente dans le récepteur. Le rapport signal sur interférence intercanal de l'image reconstruite est évalué par des simulations numériques. Les résultats d'expériences sur un prototype de système radar 3D-MIMO développé montrent que ce système peut extraire uniquement le mouvement respiratoire d'un sujet humain à 2 m de distance d'un réflecteur métallique rotatif. De plus, il s'avère que ce système peut mesurer avec succès les informations respiratoires de sujets humains endormis pendant 96.6 % de la durée totale de la mesure, à l'exception des cas de changement de posture important.

Abstract: The importance of respiratory monitoring systems during sleep have increased due to early diagnosis of sleep apnea syndrome (SAS) in the home. This paper presents a simple respiratory monitoring system suitable for home use having 3D ranging of targets. The range resolution and azimuth resolution are obtained by a stepped frequency transmitting signal and MIMO arrays with preferred pair M-sequence codes doubly modulating in transmission and reception, respectively. Due to the use of these codes, Gold sequence codes corresponding to all the antenna combinations are equivalently modulated in receiver. The signal to interchannel interference ratio of the reconstructed image is evaluated by numerical simulations. The results of experiments on a developed prototype 3D-MIMO radar system show that this system can extract only the motion of respiration of a human subject 2 m apart from a metallic rotatable reflector. Moreover, it is found that this system can successfully measure the respiration information of sleeping human subjects for 96.6 percent of the whole measurement time except for instances of large posture change.
