摘　　要：分析了电子对抗系统对未知目标干扰策略的不足,提出了基于雷达信号参数的威胁度分析方法。结合模糊理论算法,建立基于目标距离、目标速度、目标航向夹角三大变量的威胁度隶属函数,最终计算出多批目标的相对威胁等级,对提高现有电子对抗系统对于未知目标的干扰决策能力具有很高的工程应用价值。通过实例验证,该方法可行。The article analyzes the lack of jamming strategy of electronic countermeasure system against unknown targets,and proposes a threat analysis method based on radar signal parameters,combining fuzzy theory algorithm,establishes a threat membership function based on three variables:distance,speed and heading angle of a target,finally calculates the relative threat level of multi-batch targets,which is of great engineering application value for improving the jamming strategy ability of existing electronic countermeasure system against unknown targets.The method proposed in this paper is feasible through a practicle example validation.
