    摘要:

    数据链与电子支援措施(Electronic Supporting Measures,ESM)融合跟踪是 1种典型的异类多传感器信息融合。针对数据链航迹存在延迟和 ESM点迹间断情况下的数据链航迹与 ESM点迹融合跟踪,提出了复杂情况下的数据链与 ESM融合跟踪方法,并对融合跟踪的精度进行分析研究。首先,对数据进行时间对准,保证数据链和 ESM数据率一致;然后,通过构造基于不敏变换(Unscented Transformation,UT)的非线性量测转换和误差估计方法,将数据链数据对准到 ESM数据;最后,通过引入随机补偿机制对数据链延迟进行补偿,并与 ESM数据进行关联融合。实验结果表明,有延迟补偿时的融合跟踪精度取决于延迟补偿均值与实际延迟的贴近程度。结果可为信息综合处理装备的发展和设计提供借鉴。

    Abstract:

    The fusion tracking of data link and Electronic Supporting Measures (ESM) is a typical heterogeneous multiplesensors information fusion. Aiming at the fusion tracking of data link track and ESM track when the data link track has delayand the ESM track is discontinuous, the fusion tracking method of data link and ESM track under complex conditions is pro.posed, and the accuracy of fusion tracking is analyzed and studied. First, the data is time aligned to ensure that the data linkand ESM data rates are consistent; then, the data link data is aligned to ESM data by constructing a nonlinear measurementtransformation and error estimation method based on Unscented Transformation (UT); finally, the data link is compensatedby introducing a random compensation mechanism, and associated with the ESM data. The experimental results show thatthe fusion tracking precision with delay compensation depends on the closeness between the mean value of delay compensa.tion and the actual delay, which provides a reference for the development and design of integrated information processingequipment.
