Abstract

In the medical field, heart and breathing rates are obtained largely using devices that come in contact with the individual’s body. Since COVID, there has been a shift in attitude towards performing these actions contactless. To obtain vital signs contactless, we require a device that can observe periodic patterns in an individual’s chest displacement to a great degree of accuracy. A mmWave radar sensor can be used to solve this problem, which is explored in this thesis. The mmWave radar transmits a Frequency Modulated Continuous Wave (FMCW) within the frequency range of 77-81GHz. This FMCW radar is suited for the application as the high frequency enables it to pick up on smaller range variations, while also being cheaper than pulse radar in generating these signals. Using the mmWave sensor, this thesis estimated the breathing and heart rate of a stationary individual to an error percentage of 2.22% and 5.77% respectively.
