Abstract: A contactless electrocardiogram monitoring method based on a millimeter wave radar is provided, including: step S1: transmitting a millimeter-wave signal to a target to be tested and receiving an echo signal using the millimeter-wave radar; step S2: performing a signal processing on the received echo signal to extract cardiac mechanical activity data hidden in the echo signal; step S3: constructing an end-to-end network architecture for the extracted cardiac mechanical activity data, so as to complete a cross-domain mapping from a cardiac mechanical activity to a cardiac electrical activity; and step S4: based on a deep learning network architecture which has learned cross-domain mapping of the cardiac mechanical activity and the cardiac electrical activity, inputting cardiac mechanical activity data extracted at a current moment, and outputting an ECG measurement result for the current moment, so as to finally complete contactless electrocardiogram monitoring.
