▎ 摘　　要

NOVELTY - A radar-infrared-visible light multi-spectrum camouflage invisible structure includes a radar wave absorbing structure layer, an infrared heat insulation coating, an adhesive layer and a wave-transmitting camouflage net layer arranged from bottom to top. The radar wave absorbing structure layer includes an upper layer, a surface layer honeycomb core, an intermediate layer, a bottom honeycomb core, a bottom layer and a reflective layer arranged from top to bottom. USE - Radar-infrared-visible light multi-spectrum camouflage invisible structure. ADVANTAGE - The radar-infrared-visible light multi-spectrum camouflage invisible structure: has excellent radar absorbing performance in L, S, C, X, Ku, and Ka-bands, and infrared and visible light stealth functions; solves the problem of absorbing materials in radar wave band, infrared frequency band, and visible light multi-spectrum stealth; and can be prepared by a method, which is simple, controllable, and low in cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the radar-infrared-visible light multi-spectrum camouflage invisible structure, which involves: (1) preparing radar structure wave-absorbing layer by immersing the surface layer honeycomb core in an aqueous solution of wave-absorbing paint (A), spraying wave-absorbing paint (B) on the surface of the bottom honeycomb core, drying in an oven at 80 degrees C, then bonding the upper layer, surface layer honeycomb core, intermediate layer, bottom honeycomb core, bottom layer and the reflective layer, and curing at 80-100 degrees C for more than 6 hours; (2) spraying coating containing infrared absorbent on the upper layer of the radar structure wave-absorbing coating, and curing at 110-150 degrees C for more than 6 hours to prepare an infrared thermal insulation stealth layer; and (3) coating an adhesive layer on the infrared thermal insulation stealth layer, and then attaching the wave-transmitting camouflage net on the surface of the adhesive layer along the center to the four sides, compacting, and curing in a vacuum oven.
