The data utilized the IWR1642 FMCW radar and the DCA1000EVM data acquisition board from Texas Instruments. Three different environments—bedroom, shared office, and unoccupied conference room—were selected as potential scenarios for non-contact vital sign monitoring. Continuous monitoring was conducted at distances of 0.5, 1, 1.5, and 2m for 120s. The results were calculated using a 30-second data window, with 91 calculations performed during each monitoring session, starting from the 30th second and continuing until the 120th second.
