Hardware-in-the-loop simulation for MMW/IR compound guidance system is researched. A principle scheme of the simulation system is presented and a dichroic beam combiner is introduced. The key technology of the designing and producing of MMW target simulation, IR target simulation and dichroic beam combiner is expatiated and analyzed. A fractal frequency selective surface is designed to use as dichroic beam combiner. Both simulated and experiment results show that the beam combiner has high performance of stable transmission for MMW incident signal, and the average reflectivity for far IR signal reaches 85%.Furthermore, the beam combiner can be used in both 8mm and 3mm MMW/IR compound guidance system.
