基于区间重合度的雷达与ESM航迹关联算法

摘要

针对时变系统误差的情况,提出了一种基于区间重合度的雷达与电子支援措施(ESM)航迹关联算法.分析了时变系统误差对雷达与ESM测量数据的影响,将时变系统误差下航迹的不确定性转化为区间问题,通过区间的重合度来衡量雷达与ESM航迹关联程度,建立了灰色关联分析模型,实现了无需系统误差配准下的雷达与ESM航迹关联.在不同误差下进行了仿真对比,仿真结果表明,该算法能有效地实现时变系统误差下的雷达与ESM航迹关联,具有良好的鲁棒性.%Aiming at the situation with time-varied systematic errors,a gray track association algorithm of radar and ESM based on interval overlap ratio is proposed in this paper.The effect of time-varied systematic errors on the measurements of radar and ESM is analyzed and the uncertainty of tracks is turned into an interval problem in the presence of time-varied systematic errors.The correlation is measured by the interval overlap ratio and a gray model is established,which realize the track association of radar and ESM without registration.Simulation is carried out with different errors,and the results show that the proposed method can achieve the track association of radar and ESM effectively and has good robustness.
