A multi-objective track association method based on uncertainty distribution and its solution

传统航迹关联模型中通常将噪声和干扰用高斯分布来描述,而电子装备的大量使用,使得战场电磁环境日趋复杂。针对这一问题,提出了一种基于不确定分布的多目标航迹关联模型,通过引入不确定分布函数来描述航迹关联过程中的噪声及干扰,使模型更符合战场真实情况,构建了双传感器情况下的多目标航迹关联流程,并利用经典算法对不同数量目标进行了仿真验证。结果表明,在同等条件下,所提出的模型均优于传统模型,能够带来关联准确率的提升。

The noise and interference are usually described by Gaussian distribution in the traditional track association model,while the massive use of electronic equipment makes the battlefield electromagnetic environment more and more complex.To address this problem,this paper proposes a multi-target trajectory association model based on uncertainty distribution,by introducing uncertainty distribution function to describe the noise and interference in the trajectory association process,so that the model is more in line with the real situation on the battlefield,constructs a multi-target trajectory association process in the case of dual sensors,and uses classical algorithms to simulate and verify different numbers of targets.The results show that the model proposed in this paper outperforms the traditional model under the same conditions and can bring improvement in the association accuracy.
