The invention discloses an active microwave holographic security check instrument system. The active microwave holographic security check instrument system comprises a transmitting antenna assembly, a frequency synthesizer assembly, a receiving front end, a gating control panel, a processing module, a calibration system, a power supply module and a servo system. Compared with the traditional security check equipment, the active microwave holographic security check instrument system has the advantages that personnel to be subjected to security check do not stagnate, so that security check efficiency is greatly improved; security check invisibility is high; and remote monitoring characteristic can be realized. The active microwave holographic security check instrument system can be mounted on a vehicle, so that an overall structure adopts an antenna array foldable manner, and rotation of a pitch axis and an azimuth axis can be realized while a practical application occasion is considered. Compared with the traditional security check equipment, an arrangement and control mode is more flexible, and effective early warning on a violent and horrific event can be realized. A frequency modulated continuous wave system is adopted, so that transmitting power is greatly reduced, and equipment cost is reduced.
