摘要:

针对目标密集场景下敌我识别(identification friend or foe,IFF)目标与雷达目标关联问题,提出一种基于证据理论的目标关联方法。建立位置关联度模型,并基于雷达和识别器的目标方位、距离量测能力和多次量测数据生成证据及其基本概率指派,包括对多个目标多次量测形成的证据;对同一目标多次量测形成的证据进行Dempster规则组合,构建组合证据集合;基于组合证据集合最大值搜索逐步完成所有目标的关联。仿真结果表明,所提方法相比于最邻近关联方法,以相同的时间复杂度获得更高的关联正确率;相比于Kuhn-Munkres关联方法,以更低的时间复杂度,在大部分密集目标场景下获得更高的关联正确率。

Abstract:

To address the problem of association between IFF targets and radar targets in scenarios dense target scenarios, an association method based on evidence theory is proposed. A positional correlation model is established. Evidence and its basic probability assignment (BPA) are generated based on the azimuth and range measurement capabilities of the radar and IFF interrogator, as well as data from multiple measurements. Evidence derived from multiple measurements of the same target is combined using the Dempster rule to construct a combined evidence set. The association of all targets is completed sequentially based on a maximum value search within the combined evidence set. The simulation results demonstrate that, the proposed method achieves higher association accuracy than the nearest neighbor (NN) method at equivalent time complexity. Furthermore, compared to the Kuhn-Munkres (KM) algorithm, the proposed method achieves higher accuracy in most dense target scenarios with lower time complexity.

Key words: target association, association accuracy, evidence theory, basic probability assignment, identification friend or foe, complex scenarios
