Based on the theories of infrared radiation, radar absorption and scattering, combined with the presented situations of the composite passive jamming materials, a new three-dimensional radar passive jamming material coated with radar transparent infrared low emissivity material is proposed. Based on the non-combustible characteristics of the infrared coating material, the three-dimensional passive jamming material falling cannot be burned on the ground. And through researching on the matching of the jamming performance of the infrared and radar bands of the composite coatings, as well as the multi-shape reflection and absorption characteristics of the passive jamming material, the theoretical simulation and experimental tests are carried to provide theory and data supports for the infrared shielding and radar band scattering characteristics of the three-dimensional radar passive jamming material coated with radar transparent infrared low emissivity material.
