Digital motion identification method based on one-transmitting two-receiving millimeter wave radar

The invention discloses a digital motion identification method based on a one-transmitting two-receiving millimeter wave radar, and the method comprises the steps: collecting the radar original data of a digital motion, processing each frame of radar original data, and obtaining the center of gravity of a target; calculating information statistics of multiple frames of target gravity centers to obtain target features; inputting the target features into a machine learning model to serve as a classification and identification basis for performing digital actions; and inputting statistical information to carry out classification and identification on digital actions. The implementation method is simple, the overhead of computing resources is small, the digital action can be recognized under the condition that the hardware condition is a millimeter wave radar with one transmitting antenna and two receiving antennas, the method is not limited by light in the environment, and the action can be recognized more accur
