With high technology development and its extensive application in the military, the modern infrared reconnaissance capability has been continuously improved, which also promotes the development of infrared camouflage capability. For the imperfect index system of the air defense missile infrared camouflage capability and the difficulty in quantitative evaluation, a comprehensive index system is proposed. We analyze the air defense missile infrared camouflage capability from the three aspects of infrared reconnaissance capability, infrared implicit capability, and infrared false capability. The evaluation of air defense missile infrared camouflage capability is conducted by the set pair analysis model based on the comprehensive weighting method, and the method is verified through an example. The analysis results show that the construction direction of the air defense missile infrared camouflage capability is all-directional, multi-band, and systematic.
