Infrared radiation characteristics of head-on stealth missile

The application of infrared stealth technology in the stealth missile could reduce the detection probability of missile by infrared detection system. Taking AGM-158C missile as a reference, the infrared radiation characteristics of target in the head-on observation direction including target skin, target skin reflection of surrounding backgrounds and infrared radiation intensity of target tail flame were estimated, and were compared with the infrared radiation characteristics of typical subsonic missile. The analysis results show that the infrared stealth technology can significantly reduce the medium and long wave infrared radiation of the missile, especially in the medium wave band. In the design of the infrared detection system, the medium-wave infrared detector is usually used for the tail flame detection, while the long-wave infrared detector used for the missile body detection. The stealth missile using the infrared stealth technology will improve the penetration ability of the missile.
