针对交互式多模型算法中转移概率矩阵与实际运动不匹配而影响跟踪精度的问题，通过分析某型导弹的典型弹道，将弹道规律融合到模型概率转移矩阵中，然后将转移概率模糊化处理，提出了一种基于弹道规律的模糊交互式多模型算法，然后以导弹蛇形运动转至比例导引的机动过程为例进行了仿真验证，比较了典型交互式多模型算法和模糊交互式多模型算法的跟踪性能。仿真结果表明：该算法可显著提高导弹机动段的跟踪精度。

A fuzzy interactive multiple-model algorithm based on the ballistic law is proposed to im-prove the tracking precision which is degraded by the mismatch between the mode transition matrix and the target motion.The Fuzzy IMM(interactive multiple models)algorithm is better than the con-ventional IMM algorithm in the simulation of a kind of trajectory-controlled missile which maneuvers from the snake mode to the proportional homing mode.
