Abstract [en]

Ultra Wide Band ( UWB ) radar technology shows great promise for non-contact remotemonitoring of vital signs such as respiration and heart rate. Previous studies show us theusefulness of the UWB-based radar for breathing and heart rate estimation. The obstaclepenetration capabilities of UWB radar make it appropriate for applications such as humanmonitoring, detection of people and parameters of their motion inside buildings and remotediagnosis of a person’s emotional state. The use of UWB radars for vital signs monitoringpresent some challenges:• Small torso movement during the measurement may compromise results.• Respiratory signal may overshadow the heartbeat rate.• Bio-signals are not stationary.• UWB utilizes very low-low power signals that are easily overpowered by noise.Knowing these problems this thesis investigates signal processing techniques in order to overcome these challenges and detect heart rate. In particular, this thesis investigates a new type ofUWB radar which has not be considered in previous publications. The proposed methods istested under several different experimental conditions and several different subjects. Resultsindicate that this type of UWB radar can be successfully used for breathing and heart ratedetection.
