915-MHz Continuous-Wave Doppler Radar Sensor for Detection of Vital Signs

Doppler Radar Vital Signs Detection Method Based on Higher Order Cyclostationary

Due to the non-contact nature, using Doppler radar sensors to detect vital signs such as heart and respiration rates of a human subject is getting more and more attention. However, the related detection-method research meets lots of challenges due to electromagnetic interferences, clutter and random motion interferences. In this paper, a novel third-order cyclic cummulant (TOCC) detection metho...

Non-Contact Sensor for Long-Term Continuous Vital Signs Monitoring: A Review on Intelligent Phased-Array Doppler Sensor Design

It has been the dream of many scientists and engineers to realize a non-contact remote sensing system that can perform continuous, accurate and long-term monitoring of human vital signs as we have seen in many Sci-Fi movies. Having an intelligible sensor system that can measure and record key vital signs (such as heart rates and respiration rates) remotely and continuously without touching the ...

P1.8 a Comparison of Winds Measured by a 915 Mhz Wind Profiling Radar and a Doppler Lidar

Recent work has suggested that it may be possible to extract much higher quality wind information from wind profiling radars than we have traditionally expected. In particular, Gossard et al. (1998) suggested that selection of Doppler spectral peaks by a “human expert” combined with suitable data processing could yield accurate estimates of wind profiles over periods as short as a few minutes. ...

Probabilities of False Alarm for Vital Sign Detection on the Basis of a Doppler Radar System

Vital detection on the basis of Doppler radars has drawn a great deal of attention from researchers because of its high potential for applications in biomedicine, surveillance, and finding people alive under debris during natural hazards. In this research, the signal-to-noise ratio (SNR) of the remote vital-sign detection system is investigated. On the basis of different types of noise, such as...
