Non-Contact VITAL Signs Monitoring of a Patient Lying on Surgical Bed Using Beamforming FMCW Radar

open access: yesSensors, 2022
Respiration and heartrates are important information for surgery. When the vital signs of the patient lying prone are monitored using radar installed on the back of the surgical bed, the surgeon’s movements reduce the accuracy of these monitored vital ...

A Generalized Continuous Wave Synthetic Aperture Radar [PDF]

open access: yes2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017
Attention has been devoted to Synthetic Aperture Radar (SAR) for half a century. Though it is a well-proven remote sensing technique, conventional pulsed SAR has several inherent limitations. In this paper, we present a new SAR concept, called Generalized Continuous Wave SAR (GCW-SAR).

Air-borne linear frequency modulation range interrupted continuous-wave SAR for high-resolution imaging

open access: yesThe Journal of Engineering, 2019
To avoid two apertures adopted in air-borne continuous-wave (CW) synthetic aperture radar (SAR) systems, the novel air-borne linear frequency modulation range interrupted continuous wave (LFMRICW) SAR imaging mode is presented here.
