Contactless Electrocardiogram Monitoring With Millimeter Wave Radar
نویسندگان
چکیده
The electrocardiogram (ECG) has always been an important biomedical test to diagnose cardiovascular diseases. Current approaches for ECG monitoring are based on body attached electrodes leading uncomfortable user experience. Therefore, contactless drawn tremendous attention, which however remains unsolved. In fact, cardiac electrical-mechanical activities coupling in a well-coordinated pattern. this paper, we achieve by breaking the boundary between mechanical and electrical activity. Specifically, develop millimeter-wave radar system contactlessly measure activity reconstruct without any contact in. To comprehensively, propose series of signal processing algorithms extract 4D motions from radio frequency (RF) signals. Furthermore, design deep neural network solve related domain transformation problem end-to-end reconstruction mapping RF input output. experimental results show that our measurements timing accuracy events with median error below 14ms morphology Pearson-Correlation 90% Root-Mean-Square-Error 0.081mv compared groudtruth ECG. These indicate enables potential contactless, continuous accurate monitoring.

Terahertz Imaging, Millimeter-wave Radar
The millimeter wave (MMW) band of frequencies extends from 30 GHz to 300 GHz, with some fuzziness on both ends of this spectrum. The terahertz (THz) band extends from about 200 GHz to about 30 THz, despite the fact that the lower frequencies in this range are not strictly 10 Hz or higher. These bands are also variously called submillimeter, far-infrared, and near-millimeter. In recent years, th...

متن کاملBroadband Millimeter-wave FMCW Radar for Imaging of Humans
We present design and realization of a broadband FMCW Radar working in the Millimeter-Wave (MMW) region. The usable frequency range lies between 91GHz and 102GHz. We use a homodyne radar setup. Thus only one MMW source is necessary which is used for TX and LO generation simultaneously. The complex RX radar signal is calculated by a Hilbert transform in order to avoid a broadband MMW IQ mixer. A...
