SPACE-BASED TACTICAL BALLISTIC MISSILE TYPE IDENTIFICATION

摘要

This work is focused on the space-based tactical ballistic missile type identification. As mentioned in some literatures, the missile types are mainly identified by infrared radiation, missile engine off-time eigenvalue or standard ballistic trajectory. But the infrared radiation is sensitive to weather, light beam and cloud cover; the missile engine off-time eigenvalue are different according to different missile flight programs; the standard ballistic trajectory is not applicable to especially lofted and depressed ballistic trajectory. In this paper, a novel method is proposed to identify the missile types according to the brand new characteristics. By analyzing the law of the missile thrust and the mass changed over time, the paper comes to the conclusion that the maximum range and the ratio of the missile thrust to the mass are the main characteristic information to distinguish the missile types. Next, an algorithm is established to calculate these characteristics from observation data, and the fuzzy pattern recognition algorithm is introduced to fuse these characteristics. Finally, there is discussion of example calculation by use of different methods, and the results show that the method in this paper is more reliable and feasible.
