In this paper, the extraction of the life activity spectrum based on the millimeter (mm) wave
radar is designed to realize the detection of target objects and the threshold trigger module …

In biomedical Doppler radar applications, the return signal is a nonlinear frequency-
modulation (NLFM) random process whose phase conveys heart and respiration vital-sign …

Remarkable progress has been achieved in the detection of single stationary human.
However, restricted by the mutual interference of multiple humans (eg, strong sidelobes of …

Medical radar plays an important role in non-contact vital sign monitoring. However, radar is
sensitive and susceptible to noise that deteriorates signal quality, making its application …

In this letter, a phase-based algorithm based on a logarithmic method, applicable to UWB
radars and suitable to real-time monitoring, is proposed to detect the phase variations of …

Radar has been shown potentially to be used for non‐contact sensing of biosignals in a
more comfortable and easier way than wearable and contact devices. By detecting and …

Respiration and heartbeats rates are important physiological assessment indicators that
provide valid prior-knowledge for the diagnosis of numerous diseases. However, most of the …

Simultaneous multitarget vital signs measurement has become a hot issue for noncontact
vital signs perception. However, there is still challenge in the multitarget heartbeat …

This paper presents a novel approach to simultaneously monitor multi-target vital-signs
using a frequency modulation continuous wave (FMCW) radar within the resolution …

Ultra wideband impulse (UWB) radars are getting much attention in the application of remote
sensing of heart rate. UWB radar measures the heart rate by mean of the motion of thorax in …
