| abstract |
The invention relates to a vital sign detection and identity recognition system based on a millimeter wave radar, which comprises a millimeter wave radar subsystem, a radar data preprocessing subsystem, a vital sign characteristic database subsystem, an identity recognition subsystem and an intelligent interactive interface subsystem, wherein the millimeter wave radar subsystem, the radar data preprocessing subsystem, the vital sign characteristic database subsystem, the identity recognition subsystem and the intelligent interactive interface subsystem are in communication connection with each other; the radar data preprocessing subsystem decomposes a respiratory signal and a heartbeat signal in original radar data and extracts vital sign characteristic information; the vital sign characteristic database subsystem is used for storing the identity information and the corresponding vital sign characteristic information; the identity recognition subsystem learns the vital sign characteristic information, classifies and determines corresponding identity information; compared with the prior art, the intelligent interactive interface subsystem has the advantages of high practicability, privacy protection, safety and the like. |
