摘　　要：研究了将D-S证据理论应用于电子支援措施(ESM)雷-达航迹关联的模型和算法,该模型使用数据间的统计距离作为证据赋值,通过证据合成形成关联可信度矩阵,并给出了基于关联可信度矩阵的关联判决方法。仿真验证,该算法能够在一定程度上解决多目标情况下ESM测量与雷达目标关联的问题,为C4ISR系统利用ESM的属性识别结果来辅助识别雷达目标提供了一种可行的关联方法。The model and an algorithm by using Dempster-Shafer（D-S） evidence theory for electronic support measure（ESM）-radar track association are studied.The model adopts the statistical distance between data as an evidence value assignment.The dependability matrix for the association is built by evidence combination,and the method for association judgement is given based on the matrix.The simulation proves that the method can solve association problems between ESM measurement and radar targets in multi-target environment,thus it is a viable method for a C4ISR system using the result of ESM attribute identification to identify radar target.
