摘　　要：针对天基红外卫星和大型相控阵雷达各自在弹道导弹跟踪时存在的不足,结合二者特点提出了一种基于红外卫星和大型相控阵雷达的目标联合跟踪方法,建立了"高轨红外卫星和大型相控阵雷达联合跟踪"模型、"低轨红外卫星和大型相控阵雷达联合跟踪"模型,对相应算法进行了分析比较,对目标航迹数据进行了融合处理,最后通过MATLAB仿真对比研究了目标联合跟踪方法和独立跟踪方法的差异。结果表明:采用目标联合跟踪方法,能够明显改善对弹道导弹的跟踪效果。With regard to the defects of the infrared satellite and the large phased array radar in tracking ballistic missile alone,a joint target tracking method is proposed which bases on the infrared satellite and the large phased array radar. At first,the models of the "joint target tracking of SBIRS-High and large phased array radar"and the"joint target tracking of SBIRS-Low and large phased array radar"are established. Then the two algorithms are compared,and the fusion of the target tracking data is realized. At last,the difference between the methods of joint target tracking and tracking target alone is studied in MATLAB. The simulation results show that the joint tracking method can improve the effect in tracking ballistic missile.
