The invention discloses a microwave darkroom array simulation control method and system. The microwave darkroom array simulation control method includes: calibrating connected lower computer equipmentaccording to a pre-configured instrument alignment calibration table, wherein the lower computer equipment includes one or more of the following parts: a signal source, a vector network, a array plane and a turntable; arranging a microwave darkroom array according to an azimuth elevation angle of a to-be-simulated target, and detecting triplet information values which are of the target and correspond to three antenna branches in the microwave darkroom array; determining phase shift values and attenuation values corresponding to the triplet information values, and generating, on the basis of the phase shift values and the attenuation values, a phase shift control code and an attenuation control code corresponding to the microwave darkroom array at each frequency point. Therefore, the lowercomputer equipment of the microwave darkroom array is automatically calibrated, a microwave darkroom array simulation control process is modularized, thus portability and real-time performance are improved, and the method has extremely high applicability, and can apply to different microwave darkroom environments.
