Single-channel digital group target implementation method and system

The invention discloses a single-channel digital group target implementation method and system, and the system comprises a three-channel target simulator, a coarse control unit, a spherical array structure, a radiation unit, a connection cable, and an integrated simulation control system. The spherical array structure is fixedly installed on a special foundation in a microwave anechoic chamber; the radiation unit is installed on the spherical array structure, the radiation unit is sequentially connected with the coarse position control unit and the three-channel target simulator through the connecting cable, and the integrated simulation control system is used for controlling the three-channel target simulator and the coarse position control unit to work cooperatively. According to the method, angle expansion of group targets is realized in a single channel by adopting a digital scheme, the scheme has the advantages of high cost performance, less equipment quantity, simple test configuration, high test effici
