摘　　要：针对临近空间高超声速目标飞行速度快,机动特性强和隐身性能好的运动特点,为提高雷达的跟踪精度,提出一种雷达协同组网的临近空间高超声速目标跟踪算法。首先,针对雷达组网所必需解决的空间对准问题,将各雷达量测统一到地心直角坐标系,解决地球曲率对高超声速目标大区域跟踪的影响,并采用统一时间基准及内插外推等跟踪算法解决时间对准问题;其次,采用一种新的正弦模型跟踪算法来有效解决周期滑跃目标跟踪精度不高的问题。最后,通过不同雷达目标航迹的相融合来提高目标跟踪精度。仿真结果表明,改进算法具有很好的跟踪精度。In view of the characteristics of near - space hypersonic target with fast speed, strong maneuverability and good stealth performance, a tracking algorithm of hypersonic target based on radar cooperative network is proposed. Firstly, In view of the problem in space alignment of radar network, the radar measurement is integrated into Earth - Centered - Earth - Fixed coordinate system to reduce the influence of the earth curvature on tracking hyper- sonic target in large area, and the unified time datum and tracking algorithm such as interpolation extrapolation are used to achieve time alignment. Secondly, Sine model tracking algorithm is adopted to effectively solve the problem of the existing maneuvering algorithm with low tracking accuracy. Finally, the target tracks of different radars are fused to improve tracking accuracy. The simulations show that the proposed algorithm has good tracking accuracy.
