系统误差对异地配置的雷达和 ESM 航迹关联的影响

摘要

To improve the track association effect of radar and ESM sensors with systematic errors ,a heterogeneous track association model for sensors at different sites was proposed based on angle statistics . However,it was found that,when the association algorithm was used to research radar -to-ESM data association,the correct probability of radar-to-ESM data association decreased with the increasing of the radar or ESM detection accuracy.To understand the strange phenomenon,the correct,false and comprehensive association of radar and ESM sensors for multi-targets were analyzed theoretically,and Monte Carlo simulation was made to verify the correctness of the analysis .%针对系统误差下雷达和ESM航迹关联的效果较差这一问题，提出了一种基于角度统计量的异地配置的异类传感器航迹关联模型。然而，在采用该方法对系统误差下雷达和ESM航迹关联的问题进行研究时，却会出现随着雷达或ESM探测精度的提高，雷达和ESM航迹关联的正确关联概率反而下降的现象。针对这一反常现象，分别对多目标情况下雷达和ESM航迹关联的正确关联性能、错误关联性能以及综合关联性能进行了详尽的理论分析，并用蒙特卡罗仿真验证了分析的正确性。
