摘　　要：针对传统航迹关联模型中噪声描述过于理想化的问题,提出了一种新的多目标航迹关联模型。该模型通过不确定理论中的不确定对数正态分布描述航迹关联噪声,并以匀加速直线运动目标为例,重构了其运动方程与观测方程,推导了跟踪滤波流程;为了进一步验证模型的有效性和鲁棒性,使用混合噪声模拟复杂电磁环境中的各种噪声,并分别在不同噪声环境、关联算法和目标数量条件下进行了仿真验证。结果表明:所提出的改进模型具有更好的关联准确性和鲁棒性。To resolve the noise description in the traditional track correlation model is too ideal,thus a new multi-target track correlation model was proposed in this paper.The model utilized the uncertainty log-normal distribution from uncertainty theory to describe the track correlation noise.Taking a uniformly accelerated linear moving target as a case study,its motion equation and observation equation were re-constructed before the tracking filtering process was derived.To further verify the effectiveness and robustness of the proposed model,mixed noise was adopted to simulate various noises in a complex electromagnetic environment and verification under different noise environments,correlation algorithms,and target numbers was conducted.The results show that the model proposed has achieved better correlation accuracy and robustness.
