摘　　要：随着电子对抗技术的不断进步，距离多假欺骗干扰已成为制约雷达精确跟踪的一种干扰技术。文章分别在杂波环境下和距离多假目标欺骗条件下对目标建立了量测模型，仿真分析了在这两种情况下最近邻域法和概率数据关联法的多目标关联性能。仿真结果表明，在杂波环境下由于杂波分布的均匀性导致概率数据关联法性能优于最近邻域法；然而在距离欺骗干扰条件下由于距离欺骗干扰的线状分布导致概率数据关联法性能反而不如最近邻域法。With the progress of electronic countermeasure technique, deceptive jamming has become one of the techniques restricting radar tracking target accurately. In this paper, the target measurement models are established under the condition of clutter environment and range deception jamming respectively. The multi-target association algorithm performance is studied by computer simulation in both cases above of the nearest neighbor domain method and probabilistic data association method. The simulation results show that in clutter environment, due to the uniformity of clutter distribution the performance of probabilistic data association method is better than nearest neighbor domain; however, in the presence of range deception jamming the performance of probabilistic data association is far less than the nearest neighbor domain method instead due to the linear distribution of the range deception jamming.
