Metamaterials after years of development, in various fields shows its unique charm. This paper, based on the FSS with random distributed patches, combined with digital camouflage, proposes a model for processing realize multiband stealth realization. It not only reserved the digital camouflage of visible light stealth performance, also has FSS in microwave frequency band stealth effect, and it is concluded that the corresponding simulation results. To counter the multiband detection, the fusion type FSS provides an effective method.
