摘　　要：针对目前分布式航迹融合系统尚未形成一套标准的性能评价指标体系,以及常用精度指标存在的问题,对分布式航迹融合系统评价指标体系进行了优化。使用最佳基数线性分配度量标准(COLA)代替原有的精度指标,对已有的精度指标进行优化,提出了融合COLA精度指标,并通过分析评估对象,依据构建原则初步构建评价指标体系,然后根据仿真实验获得的实验数据和粗糙集属性约简的性质对指标体系进行筛选优化,最终构建了一套较为完整、客观公正的评价指标体系。仿真实验结果表明,优化后的指标体系可以有效以及更加适用地评价分布式航迹融合系统性能。In view of the present distributed track fusion system had not yet formed a set of standard performance evaluation index system,and the problem of the common precision index,the evaluation index system of distributed track fusion system was optimized.The Cardinalized Optimal Linear the Assignment(COLA)was used to instead of the original precision index,and the existing precision index was optimized,then the fusion COLA precision index was put forward.And by analyzing the evaluation object,the evaluation index system was initially constructed according to the construction principle.Then,according to the experimental data obtained by the simulation experiment and the nature of the rough set attributed reduction to screen the index system.As a result,a set of relatively complete,objective and fair evaluation index system was built.Simulation results showed that the optimized index system could evaluate the performance of distributed track fusion system effectively and more applicable.
