Millimeter wave active phased array calibration method and system

The embodiment of the invention discloses a millimeter wave active phased array calibration method and system. The method comprises the following steps: opening a reference channel to send out a reference signal, and determining an amplitude matrix and a phase matrix corresponding to the reference signal; configuring a serial number for each to-be-measured channel of the millimeter wave active phased array, and circularly executing a first preset operation according to the configured serial number to obtain a first measurement amplitude value and a first measurement phase value of each to-be-measured channel; when it is determined that one traversal is completed on each to-be-measured channel, determining a first amplitude error value corresponding to each to-be-measured channel based on the first measurement amplitude value of each to-be-measured channel; based on the first measurement phase value of each to-be-measured channel, determining a first phase error value corresponding to each to-be-measured chann
