Ultra-wideband (UWB) pulse Doppler radars can be used for noncontact vital signs
monitoring of more than one subject. However, their detected signals typically have low …

Cardiopulmonary activity measured through contactless means is a hot topic within the
research community. The Doppler radar is an approach often used to acquire vital signs in …

Non-contact vital sign monitoring has been an important research topic recently due to the
ability to monitor patients for an extended period especially during sleep without requiring …

This paper discusses the use of a nonlinear sensing technology based on radio frequency
(RF) intermodulation response to track both the vital signs and location of human subjects …

The design and development of a hybrid Gaussian pulse radar transceiver, including
transmitter and receiver, is presented. The transmitter is realized using a transistor-based …

In this study, a quasi‐real‐time human respiration detection method with prominent signal‐to‐
noise‐and‐clutter ratio (SNCR) improvement is proposed to increase performance of ultra …

There is a need to detect vital signs of human (eg, the respiration and heart-beat rate) with
noncontact method in a number of applications such as search and rescue operation (eg …

This letter presents a periodic leaky-wave array antenna with circular polarization at
millimeter-wave frequencies. The antenna is designed on the low-loss planar Goubau …

A novel ultra-wideband (UWB) linear array human respiration model and detection method
is proposed to obtain vital sign feature (VSF) including azimuth, range, and respiration …

Ultra wideband impulse (UWB) radar for vital signs measurement applications is getting
much attention because it is a contactless method. However, the heartbeat signal is usually …
