Millimeter wave heart rate monitoring device

The invention discloses a millimeter wave heart rate monitoring device which comprises a power module, a millimeter wave heart rate monitoring module and a retrodirective antenna array module. The power supply module provides energy for the millimeter wave heart rate monitoring module, and the millimeter wave heart rate monitoring module transmits millimeter wave signals and receives echo signals enhanced by the direction backtracking antenna array for processing and displaying. The direction backtracking antenna array module receives millimeter wave signals transmitted by the millimeter wave heart rate monitoring module and automatically tracks the millimeter wave signals. The direction backtracking antenna array module is adopted to enhance millimeter wave echo signals, the problems that existing heart rate monitoring is low in precision, short in distance and the like are solved, meanwhile, the system can well adapt to the human tissue environment, and a foundation is laid for achieving high-performance mi
