摘要
We propose a unique approach to extract and visualize human respiration and pulse rate using phase tracking mm-wave FMCW radar. This study focuses on simultaneous measurement of three human test subjects arranged with diverse range and azimuth positions in the radar view. We aim a Texas Instruments A WR1642™ and DCA1000EVM™ radar assembly toward three test subjects and measure the waveform phase delay across time. We then employ the short-time Fourier transform with overlapping windows to create spectrogram images from which the vital signs can be interpreted using human vision or image processing software.
