Tx, is used to measure the velocity of two. An IF signal is calculated by mixing the transmitted and received signals. Each IF signal undergoes an FFT to find a peak corresponding to the range. A second FFT transforms the set of Range-FFT results so that two objects can be distinguished by their phase displacements, which correspond to their different velocities. Therefore, the heart rate can be distinguished from the breathing rate. (a) A frame of transmitted signals are used to (b) detect the
... d to (b) detect the range of the chest, which can be (c) transformed into heart rate and breathing rate using FFTs. The IWR1443 mmWave radar sensor obtains heart rate measurements by detecting miniscule movements of the chest caused by the heart's pulse and breathing. Results A Graphical User Interface was developed using C and MATLAB to display a cardiac waveform and a graph of heart rate values in apparent real-time. Experiments using moving averages were performed to increase the accuracy of the sensor's values. Conclusion This relatively new mmWave radar technology can be used fairly accurately for the pulse rate monitoring in neonates, children, burns patients or for sleep studies. Being contactless, it prevents skin damage and burns. We recommend the 'Paediatrics 2040' project to encourage the Use and further Research of such monitoring devices to decrease risks.
