摘　　要：多辐射源跟踪任务受辐射源天线扫描方式、工作参数变化等因素影响,在目标种类、数量等方面存在一定的时变特征。对该特征的适应能力是评估电子支援措施(electronic support measures,ESM)辐射源跟踪能力的一项重要指标。据此,首先建立了一种迭代式时频扫描方案优化模型。然后,以评估ESM对多辐射源跟踪任务时变特性的适应能力为目标,提出了一种基于可行域的性能评估方法。仿真实验结果表明,在不同类型目标数量动态变化过程中,所提方法给出的评估结果都能与扫描方案实际性能保持一致,具备准确的动态评估能力。The multiple emitters tracking task is influenced by factors such as the sweeping method of the radiation source antenna and changes in working parameters,and there are certain time-varying characteristics in terms of target types and quantities.The adaptability to this feature is an important indicator for assessing the tracking ability of electronic support measures(ESM)emitters.Based on this,an iterative time-frequency sweeping scheme optimization model is established firstly.Then,with the goal of assessing the adaptability of ESM to the time-varying characteristics of multiple emitter tracking tasks,a performance assessment method based on feasible zone is proposed.Simulation experiment results show that in the process of dynamic changes in the number of different types of targets,the assessment results provided by the proposed method can be consistent with the actual performance of the sweeping scheme,and have accurate dynamic assessment capabilities.
