摘　　要：针对传统滤波算法在处理目标复杂机动时非线性逼近能力不足、跟踪精度下降等问题,提出一种强跟踪容积卡尔曼滤波(STCKF)方法。首先,根据战斗机规避空空导弹的机动特征,建立了蛇形机动和桶滚机动两种目标运动模型;其次,引入强跟踪滤波(STF)以增强容积卡尔曼滤波(CKF)对系统状态突变等不确定因素的能力;然后,将STCKF应用于导弹末制导目标运动参数估计中,并通过与CKF、无迹卡尔曼滤波(UKF)和粒子滤波(PF)的对比仿真分析验证了该方法的有效性。仿真结果表明,STCKF具有较强的鲁棒性和系统自适应能力,尤其在目标机动突变时其跟踪误差相比CKF减小约10%,能够满足空空导弹末制导高精度和快速响应要求。A strong tracking cubature Kalman filter(STCKF)method is proposed to overcome the challenges of insufficient nonlinear approximation capability and decreased tracking accuracy of traditional filtering algorithms in dealing with complex maneuvering targets.Firstly,models for snake maneuver and barrel roll maneuver are developed based on the maneuvering characteristics of fighter aircraft evading air-to-air missiles.Secondly,strong tracking filter(STF)is introduced to enhance the ability of cubature Kalman filter(CKF)to handle sudden changes in system states and other uncertainties.Then,STCKF is applied to estimate the motion parameters of missile terminal guidance target,and its effectiveness is validated through comparative simulation analysis with CKF,unscented Kalman filter(UKF),and particle filter(PF).Simulation results indicate that STCKF has enhanced robustness and adaptive capabilities,especially when the target maneuver suddenly changes,its tracking error is reduced by about 10%compared to CKF,which can meet the high precision and rapid response requirements of air-to-air missile terminal guidance.
