NON-CONTACT DIAGNOSTIC SYSTEM FOR SLEEP APNEA SYNDROME USING TWO MICROWAVE RADARS

摘要：

　　There were two key problems in applying Doppler radar to a diagnosis system for sleep apnea syndrome. The first is noise associated with body movement and the second is the body position in the bed and the change of the sleeping posture. We propose a new automatic gain control and a real-time radar-output channel selection method which is based on a spectrum shape analysis. A prototype of the system was set up at a nursing home and field tests were carried out with eight subjects. Despite the subjects engaging in frequent body movements while sleeping, the system was quite effective in the diagnosis of sleep apnea syndrome (r=0.87).
