A fast calibration test system and method for a phased-array antenna, which belongs to the technical field of antenna measurement, relates to a near-field test system, and relates in particular to the fast calibration and a directional diagram test on a phased-array antenna. The system comprises an upper computer module, a switch module, a synchronization control module, a signal source module, a power amplifier module, a low noise amplifier module, a phased array antenna to be tested, a power supply module, a calibration control module, a scanning module, a signal conditioning module and a vector network module; on the basis of a pulse synchronization mechanism, the loading delay of a wave control code is shortened by using real-time calculation method; the channel calibration of the phased-array antenna under various frequencies may be completed by means of two rounds of scanning, and a directional diagram test on the phased-array antenna under a combination of various frequencies and directional angles may be covered by means of one round of scanning.
