Non-Contact Heart Rate Monitoring Based on Millimeter Wave Radar

Non Contact Heart Monitoring

Heart rate is, among the many vital signs (respiration rate, blood oxygen saturation, arterial blood pressure, etc.), one of the most commonly measured and monitored. Whatever will be the sensing principle or the monitoring method used, data referred to the heart rate can be considered the primary vital sign information which is needed on a patient approach in both emergency and clinical situat...

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...

A New Kind of Non-acoustic Speech Acqui- Sition Method Based on Millimeter Wave Radar

Air is not the only medium that can spread and can be used to detect speech. In our previous paper, another valuable medium — millimeter wave (MMW) was introduced to develop a new kind of speech acquisition technique [6]. Because of the special features of the MMW radar, this speech acquisition method may provide some exciting possibilities for a wide range of applications. In the proposed stud...

Millimeter-Wave Circuit Design for Radar Transceivers

The 4 GHz Bandwidth Millimeter - Wave Radar

The landmark construction of the Advanced Research Projects Agency (ARPA)–Lincoln C-band Observables Radar (ALCOR) at Kwajalein Atoll in 1970 sparked significant interest in the ballistic missile defense (BMD) and satellite-identification communities [1]. ALCOR's 50 cm range resolution using 512 MHz bandwidth data confirmed the viability of valuable new BMD discrimination techniques and provide...
