| titleOfInvention | A method for detecting human breathing and heartbeat based on millimeter-wave radar |
| abstract | The invention discloses a method for detecting a person's breathing and heartbeat based on a millimeter wave radar, which belongs to the field of radar signal processing. signal; form a sampling matrix by de-slope processing and discrete; then, perform fast Fourier transform on each row of the matrix to obtain the time-distance image Rp(m,n); and use each column of Rp as a distance unit, using The center of the constellation diagram eliminates the clutter of all distance cells; then, the average value of the noise power of each range cell is used as the threshold, the cell average constant false alarm is used to detect the target existing in each range cell, and the Doppler solution is performed according to the position of the target. Finally, reconstruct the separated waveforms of respiration and heartbeat on the demodulation result; estimate the cycle of a single respiration or heartbeat in the reconstructed waveform; output the respiration and heartbeat waveform and real-time frequency estimation of the pulse signal; the algorithm of the present invention is simple and reduces the amount of calculation . |
