Abstract
Ballistic target recognition occupies a unique and important position in many application fields of target recognition because of its challenge and important position of ballistic missile defense in national security; recognition time of defense system becomes very limited because of ballistic missile high-speed flight; recognition distance of defense system is also due to stealth technology. The integrated application of active jamming and passive decoy greatly increases the difficulty of identification of defense system. Because of its special status and challenge, ballistic target recognition has attracted wide attention of researchers at home and abroad, making it one of the most important issues in infrared target recognition research at home and abroad. In this paper, the infrared characteristics of a ballistic missile warhead target/decoy are analyzed, and the corresponding penetration measures are put forward according to the analysis results.
Highlights
In order to improve the penetration capability of ballistic warhead, a large number of sub-warheads are formed in the middle of the ballistic missile by means of warheads miniaturization and divergent multi-warheads technology, which saturates the identification and fire control capability of the defense system [1]

Summary
In order to improve the penetration capability of ballistic warhead, a large number of sub-warheads are formed in the middle of the ballistic missile by means of warheads miniaturization and divergent multi-warheads technology, which saturates the identification and fire control capability of the defense system [1]. It is very necessary to analyze the infrared radiation characteristics of the warhead target/background in the middle of the trajectory. Taking the warhead target in the middle of the trajectory as an example, the heat source on the target surface includes internal heat source and external heat source. While the ballistic missile trajectory is near ground flight, the main external heat sources include the earth and the sun. They heat the warhead from the surface of the warhead/bait. Aiming at the temperature difference between the balloon decoy and the balloon equipped with warhead, this paper puts forward some measures to eliminate the difference, which can reduce the probability of the true warhead being identified by the infrared detector
