To meet the requirements of multiband compatible camouflage, a new composite vegetation camouflage material that can realize multiband compatibility of visible light, infrared, and radar was fabricated by reasonably matching various materials and a multi-functional layer structure. The absorbing properties of the camouflage material were evaluated by a radar wave shielding effectiveness and reflectivity test. The visible and thermal infrared camouflage properties of the camouflage material were tested by an imaging method. The results show that the camouflage material has good radar wave attenuation performance, and the absorption bandwidth at values of 5dB or more is as high as 3.9GHz. The texture, color, brightness, and thermal map of the surface layer of the vegetation camouflage material are close to the background values, and the thermal insulation effect is evident, enabling good visible and infrared camouflage effects.
