Anti-camouflage capacity study of THz

Based on the characteristics of terahertz wave, the ability of THz for uncovering target covered by camouflage coating is studied. Firstly, the paper introduces the camouflage coating classification and reflectivity. Secondly, a coating reflection characteristic calculation model is established on conditions of smooth surface with methods of matrix optics. Finally, according to the calculation model, the reflectance of infrared coating and laser coating in different wavebands including 337μm terahertz wave was calculated. According to the calculating result, it’s indicated that THz has better ability to penetrate through coating than IR ; meanwhile, it’s also indicated that THz has the ability for uncovering target on some conditions.
