Study On Formula And Radiant Characteristics Of Infrared Decoy Under Carbon Fiber

In this situation that the traditional infrared is not effectively against the infrared-radar guided weapons, based on carbon fiber can scatter millimeter-wave effecttly, this article carried out the research on formula and radiant characteristics of infrared decoy under carbon fiber. According to mechanism of infrared interference and theories of infrared radiation, we changed the radiant area with using carbon fiber body, improved the infrared decoy’s capacity of against the infrared radar guided system.Based on the characterists of the pyrotechnic infrared decoy, we proposed the select principle of the components, designed some formulas of infrared decoy that have different burning characteristics, and determined their radiant characteristics by Fourier Transform infrared spectroscopy and infrared thermovision. At last, we selected three infrared decoys with different burning temperature and carried out next research on the change of radiant characteristics under carbon fiber.The study on the variation about the burning temperature、radiant area、infrared spectral radiant luminance is carried under carbon fiber, and we also discussesed the impact of the ingredient and the combustion to infrared spectral radiant luminance, and so optimized the three allocated proportion of the powder. At the same time, we studied the infiuence of CFRP to infrared spectral radiant luminance. The results indicate that infrared radiant properties of infrared decoy under carbon fiber is significantly improved, especially in the far infrared band there is very obvious radiant characteristics, meanwhile increasing the mass per unit area of CFRP and improving the CFRP preparation closeness are conducive to enhancing infrared radiant output.
