摘要

当前防空反导场景下，目标突防手段复杂多样。雷达跟踪密集多目标时，易受电磁干扰、群目标遮挡、地形遮蔽等影响，多雷达对同一目标航迹的关联易出现混批、换批问题，导致目标关联一致性下降，降低多雷达融合情报质量。针对上述问题，本文利用多雷达测距精度高于测角精度的特征，提出基于多雷达量测匹配的目标航迹关联方法，采用最小二乘实现多雷达距离交叉定位，由定位解计算目标相对于雷达的方位和俯仰角度，通过统计各雷达角度量测与定位解之间的误差分布，辅助判断多雷达对同一目标的关联跟踪，提升航迹关联一致性。仿真结果验证了所提方法的有效性。

Abstract

In the current air defense and anti-missile scenario

the target penetration means are complex and diverse. In the intensive multi-target tracking

the radars are susceptible to electromagnetic interference

group target occlusion

terrain occlusion

etc.

and the association of multiple radars with the same target track is prone to the problem of mixed batch and batch change

which leads to the decline of the consistency of target association and the reduction of the quality of multi-radar fusion intelligence. To solve the above problems

this paper makes use of the characteristics that the range accuracy of multi-radar is higher than the angle measurement accuracy

and proposes a target track association method based on multi-radar measurement matching. First

the least square is adopted to achieve multi-radar distance cross positioning. Then

the orientation and pitch angle of the target relative to the radar are calculated from the positioning solution

and the error distribution between the measurement and the positioning solution is calculated by statistics. It helps to judge the correlation tracking of multiple radars to the same target and improve the consistency of track association. Finally

the simulation results verify the effectiveness of the method.
