机载ESM与雷达航迹融合仿真系统研究

机载电子对抗侦察（ESM）和雷达已成为机载平台上获取目标信息的重要传感器。针对机载平台的特点模拟工程实践,从航迹配准、航迹关联和航迹融合三个阶段给出了一套仿真计算过程,构建了一个多参数航迹融合仿真模型。在航迹配准中主要考虑ESM传感器和雷达航迹数据之间的时空对齐问题,航迹关联中分析了基于统计理论的、基于模糊分析的和基于快速判别的三种航迹关联算法,在航迹融合中采用一种快速的加权融合的方法。仿真实验中给出了一种衡量不同航迹关联算法性能的评估计算方法,比较了在不同参数环境下三种航迹关联算法的性能及航迹融合的效果。最后给出了一些实验结论和工程实践性的建议,具有一定的工程参考意义。

Simulation of Track Fusion of Airborne ESM and Radar

Electronic support measures（ESM） and active radars have already become the most important sensors on airborne platform for acquiring target information.A multi-parameters model based on a series of simulation computations for track fusion of airborne ESM and active radar is proposed in this paper,including track registration,track correlation and track fusion.The time-space registration based on coordinate transform and interpolation is mainly considered for track registration.For track correlation,three track correlation algorithms are well analyzed,which are based on statistic,fuzzy analysis and fast judgment separately.A fast linear weighting fusion method is given for track fusion.In the experiment,an evaluation method for track correlation algorithms is proposed and a comparison between three track correlation algorithms with different parameters is given.The results have also shown that the fusion precision is better than that of active radar or ESM.Finally,several constructive conclusions are made for practical engineering applications.
