摘要:

针对在远距离密集目标情况下, 因角度维误差导致目标空间定位误差变大而航迹误关联率较高的问题, 提出一种基于目标量测误差分布的航迹抗差关联算法。首先在分析目标量测误差空间概率分布特征的基础上, 定义了与目标同一性密切相关的视同因子; 然后利用关联目标对与雷达之间的几何关系、目标量测距离和雷达站址等先验信息, 基于模糊数学理论中的高斯隶属度函数, 计算得到目标航迹之间的航迹关联度和航迹关联代价矩阵; 最后利用经典分配法进行航迹关联判定。仿真结果表明, 所提算法航迹误关联率低、抗差性好, 且不受目标数目变化的影响。

Abstract:

In the case of long-range and dense targets, aiming at the problem of high track error correlation rate due to large spatial positioning error of target caused by angle dimension error, an anti-bias track association algorithm based on target measurement error distribution is proposed. Firstly, based on the analysis of the spatial probability distribution characteristics of the target measurement error, the algorithm defines the reckon factor closely related to target identity. Then, using the geometric relationship between the associated target pair and radar, the measurement distance of target, the radar site and other prior information, the track association degree and track association cost matrices between the target tracks are calculated based on the Gaussian affiliation function in fuzzy mathematics theory. Finally, the classical allocation method is used to determine the track correlation. Simulation results show that the proposed algorithm has low track error correlation rate and good robustness, and is not affected by the number of targets.

Key words: track association, error distribution, affiliation function, multidimensional allocation
