Problems solved by technology

Although this scheme can realize the Ku / Ka / W three-band simulation on the same spherical array, it cannot realize the triplet composite simulation of the above three bands

[0009] It can be seen from the above scheme that the existing Ku / Ka / W three-band array scheme has shortcomings, and it cannot realize the triplet composite simulation of the Ku / Ka / W three-band, and cannot meet the three-band composite simulation in the current laboratory environment. The need for test and test severely restricts the development of radio frequency simulation technology and the simulation test of composite guidance equipment
