摘　　要：为了辨别空战过程中敌方来袭导弹的导引律,准确打击目标,提出了一种基于多模型自适应估计的导弹导引律辨识方法。首先,采用二自由度质点模型建立了导弹的运动方程,并确立雷达的量测方程;其次,建立了基于并行UKF滤波、模型概率更新和状态估计混合输出的多模型自适应估计算法;最后,在给定导弹和战机初始对抗态势的条件下进行建模仿真,仿真主要针对三种常用的导引律,对其类型和参数进行辨识。仿真结果表明,多模型自适应估计方法能够有效的辨识导弹导引律的类型和参数,为准确打击来袭目标提供了保障。The method of missile guide regular identification based on multi -model adaptive estimation was pro- posed to distinguish the regular of enemy missile. First, the motion equation of missile was established using two - degree freedom mass model, and the measurement equation of radar was confirmed. Then, the algorithm of multi - model adaptive estimation was built based on parallel UKF filter and model probabilities updating and mixed output of station. Last, the simulation was carried out under the condition of missile and battle plane＇s initial confrontation situ- ation. The simulation mainly estimates types and parameters of the three commonly guide regulars. The results show that the method is effectively to estimate types and parameters.
