Short summary
Monitoring vital signs without direct contact improves patient comfort and reduces measurement disturbances. Our research explores a radar-based approach to detect heartbeats without sensors attached to the body. Using a 24 GHz radar system, we developed advanced signal processing methods to ensure accurate detection. The results closely match conventional ECG (electrocardiography) measurements, demonstrating the potential of radar technology for future medical and home-care applications.
