摘　　要：针对弹道导弹突防过程中施放的有源距离假目标干扰给反导雷达跟踪系统带来的挑战,提出了一种改进的基于欺骗参数扩维估计的弹道目标跟踪方法.首先,推导了球坐标系下真假弹道目标的普适动力学方程,建立了基于欺骗参数扩维估计的弹道目标跟踪状态方程和量测方程.然后,利用求容积卡尔曼滤波器(CKF)实现免微分计算,并采用联合概率数据互联(JPDA)算法实现航迹与点迹之间的数据关联.最后,通过对距离欺骗参数的估计结果设计干扰鉴别算法,实现跟踪和干扰鉴别的一体化和实时性.仿真结果表明,该方法不仅拥有良好干扰鉴别能力,且有较高的跟踪精度.An improved ballistic target tracking method using deception parameter extended dimension estimation is proposed to address the challenges posed by active range false target interference during ballistic missile penetration to the anti-missile radar tracking system.Firstly,the universal dynamic equations of true and false ballistic targets in spherical coordinate system are derived,and the ballistic target tracking state equation and measurement equation based on the deception parameter extended dimension estimation are established.Then,the cubature Kalman filter(CKF)is used to achieve differential-free calculation,and the joint probabilistic data association(JPDA)filter is used to achieve plot-track data association.Finally,an interference identification algorithm is designed based on the estimation results of range deception parameters,achieving the integration and real-time performance of tracking and interference identification.The simulation results show that the proposed method not only has good interference discrimination ability,but also has high tracking accuracy.
