| description | The invention provides a non-contact electrocardiogram monitoring method and system based on millimeter wave sensing. The method comprises the steps that a current original signal of a measured target is collected in a non-contact mode from a thoracic cavity area of the measured target in a millimeter wave sensing mode; performing frequency domain filtering on the original signal based on a beam forming mode to extract a complex signal corresponding to a heart region of the measured target; and inputting the complex signals into a preset electrocardio cross-modal mapping model, so that the electrocardio cross-modal mapping model outputs electrocardio monitoring result data of the measured target. According to the application, heart activity key information such as electromagnetic wave frequency deviation and amplitude change possibly caused by heart electrical activity can be prevented from being lost, the comprehensiveness and reliability of focusing of the heart activity can be effectively improved, and the |
