Abstract: Several kinds of characteristics are adopted to identify middle ballistic target group by characteristics’ stability principle; for these characteristics, physical meaning is clear, extraction difficulty is low, separability is strong and value fluctuation is small. Firstly, according to characteristics’ variation law, fuzzy recognition model of real warhead is established and basic probability assignment of different evidences is completed. Then, the conflict coefficient is redefined by using the complementarity between classical conflict coefficient and the distance function in describing evidence conflict, and conflict or lower confidence evidence is revised as well. Lastly, the combination of fuzzy function and improved evidence theory is applied to middle ballistic target recognition by setting simulation conditions. Simulation results show that the proposed method can identify the real warhead successfully.

Key words: ballistic target recognition, evidence theory, fuzzy function
