Kepentingan sistem pemantauan pernafasan semasa tidur telah meningkat kerana diagnosis awal sindrom apnea tidur (SAS) di rumah. Kertas kerja ini membentangkan sistem pemantauan pernafasan mudah yang sesuai untuk kegunaan rumah yang mempunyai julat sasaran 3D. Resolusi julat dan resolusi azimut diperolehi oleh isyarat pemancar frekuensi berperingkat dan tatasusunan MIMO dengan pasangan kod jujukan M yang diutamakan dua kali ganda dalam penghantaran dan penerimaan, masing-masing. Disebabkan penggunaan kod ini, kod jujukan Emas yang sepadan dengan semua kombinasi antena dimodulasi secara setara dalam penerima. Isyarat kepada nisbah gangguan antara saluran bagi imej yang dibina semula dinilai dengan simulasi berangka. Keputusan eksperimen ke atas prototaip sistem radar 3D-MIMO yang dibangunkan menunjukkan bahawa sistem ini boleh mengekstrak hanya gerakan respirasi subjek manusia 2 m selain daripada reflektor boleh berputar logam. Selain itu, didapati bahawa sistem ini berjaya mengukur maklumat pernafasan subjek manusia yang sedang tidur untuk 96.6 peratus daripada keseluruhan masa pengukuran kecuali untuk keadaan perubahan postur yang besar.

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.
