Millimeter wave radar antenna phase calibration method, apparatus and device, and storage medium

The invention discloses a millimeter wave radar antenna phase calibration method and device, equipment and a storage medium. According to the invention, the radar target simulator is controlled to simulate the to-be-measured target according to the target distance, the speed and the radar reflection area; controlling the millimeter-wave radar to rotate at a constant speed to enable the to-be-detected target to be located at different detection angles of the millimeter-wave radar; controlling the cloud platform to send a trigger signal to obtain echo data; acquiring instruction time delays of sending trigger signals by the millimeter wave radar at different detection angles; performing angle compensation on the detection angle of the millimeter-wave radar according to the instruction time delay and the rotation angular velocity of the millimeter-wave radar; obtaining phase information of each to-be-calibrated antenna channel in the echo data; and obtaining a phase compensation coefficient of each to-be-calibra
