Portable sub-THz and THz radar system for remote physiological parameters detection and method with harmonic and fundamental components

This invention describes a portable radar system that uses very high-frequency radio waves, specifically between 0.03 and 3 THz, to remotely measure a person's vital signs, such as heart rate. It works by sending these waves towards a person's body and then analyzing the reflected signals to detect tiny, rhythmic movements caused by internal physiological processes. The system filters out noise and isolates these subtle patterns to determine parameters like heart rate and its variations, which can then be sent to a cloud system.
