Systems and methods for monitoring vital signs (e.g. heartbeat, respiration) using FMCW millimeter wave radar are disclosed herein. A transceiver is used t... Z Flaherty 被引量: 0发表: 2022年 Non-Contact Monitoring of Human Vital Signs Using FMCW Millimeter Wave Radar in the 120 GHz Band...
Heart rate measurement based on radar is an effective method for noncontact monitoring of human vital signs. However, the heart rate signal obtained from the radar is subject to noise interference due to imperfect circuit characteristics. To tackle this challenge in heart rate detection by micro-Dop...
The accurate sensing of the location of specific objects in an indoor setting is critical for applications including robotic feedback control and non-intrusive structural integrity monitoring. Current optical and ultrasound approaches often suffer from i
We propose a novel appliance operating-status detection system called HomeOSD, which utilizes mmWave radar technology. As far as we know, HomeOSD stands out as the first non-contact system capable of simultaneously monitoring the operating status of multiple appliances without interference from human ...
For the first time, we demonstrate that it is possible to use a non-contact millimeter-wave radar sensor to detect this micron-scale intrusive drilling while highway-speed vehicle movement shakes the container. With the millimeter-wave radar monitoring the microdoppler signature of the container’...
It overcame the inherent limitations of a conventional single monostatic radar-based HAR and outperformed it by 6%. Keywords: activity recognition; data fusion; distributed mmWave MIMO radar; fall detection; feature extraction; micro-Doppler signature; mean Doppler shift; support vector machine...
For military and security purposes, they can be used to detect concealed electronic devices [13,14]. They have also been applied for detecting vital signs for health monitoring [15,16,17] and insect tracking using harmonic tags [18,19,20,21]. Recent studies have presented nonlinear radar ...
Beamforming is particularly valuable for 5GNR as the higher frequency mmWave RF is subject to fading over authentication loss and distance caused by objects hitting (e.g., vehicles, buildings, etc.) [20,21]. A more coordinated beam of RF energy helps to guarantee a more prominent probability...
