Short summary
A radar working in the 24 GHz ISM-band in a frequency modulated continuous wave mode has been used for vital sign monitoring of the heart beat and the breathing rate. The observation is hereby contactless with the patient sitting straight up in a distance of 1–2 m to the radar. A mathematical method to calculate the heart beat and breathing rate is presented. The results are compared with classical ECG measurement equipment.
