The invention belongs to the field of an alignment calibration technology of a radio frequency simulation system antenna array, and discloses an alignment calibration device and alignment calibration method of a multi-frequency-point antenna array. The alignment calibration device of the multi-frequency-point antenna array, employed by the method, comprises an alignment calibration control management module, an alignment calibration microwave signal source, a four-speaker receiving antenna, a receiver module and a vector network analyzer, wherein the four-speaker receiving antenna is connected with the alignment calibration control management module through the receiver module and the vector network analyzer, and the alignment calibration control management module is respectively connected with a local oscillation microwave signal source, the alignment calibration microwave signal source, a radio frequency control circuit, an antenna array management module of an aligned and calibrated antenna array system, a rotary table control module of an auxiliary measuring device and the like through a netting twine so as to form a local area network type antenna array alignment calibration device. According to the invention, the alignment calibration work of multiple preset frequency points and channels can be finished through alignment calibration at one time, such that the defect of great equipment wear and tear generated when time consumed for alignment calibration increases exponentially as alignment calibration frequency points are increased is solved. The structure is simple, the reliability is high, and the manufacture cost is low.
