摘　　要：针对单飞行器采用无源探测手段对拦截弹主动段进行弹道估计的问题,提出一种基于动力特征模板的多模型自适应无迹卡尔曼滤波(MMAE-UKF)算法。在观测信息不完备的条件下,通过引入拦截弹动力特征模板,将飞行程序角模型设计参数与发射方位角增广为目标状态分量,基于程序角模型和动力特征模板构建非线性MMAE模型集,采用MMAE-UKF算法对拦截弹的程序角模型和设计参数进行辨识,同时对拦截弹主动段运动状态进行估计。仿真结果表明,算法能够快速准确辨识出拦截弹主动段采用的程序角模型及设计参数;与传统的增广状态滤波算法相比,运动状态估计误差显著减小,滤波稳定速度大幅度提高。An Unscented Kalman Filter with multi model adaptive estimation algorithm(MMAE-UKF)based on dynamic characteristic template is proposed to solve the problem of trajectory estimation of interceptor in boost phase by using passive detection method for single aircraft.Under the condition of incomplete observation information,by introducing the interceptor dynamic characteristic template,the design parameters of flight program model and launch azimuth angle are expanded to target state components.Based on the flight program model and dynamic characteristic template,a nonlinear MMAE model set is constructed.The flight program model and design parameters of the interceptor are identified using the MMAE-UKF algorithm,and the motion state of the interceptor in boost phase is estimated.The simulation results show that the algorithm can quickly and accurately identify the flight program model and design parameters used in the boost phase of the interceptor.Compared with the traditional expanded state filtering algorithm,the motion state estimation error is significantly reduced,and the filtering stability speed is greatly improved.
