摘　　要：针对无人机宽带高功率电磁脉冲易损性问题,以四旋翼无人机为研究对象,对其结构、功能进行分析,利用电磁敏感机理对接收机进行了敏感度分析,利用场线耦合进行了负载50Ω终端响应电压计算,进行了易损性计算,得到了场强、重复频率与毁伤概率的关系。利用系统级效应试验得到了3种电磁脉冲源作用下的毁伤阈值。研究表明:最易受到干扰毁伤的部件为接收机和GPS,重复频率增加,场强阈值降低,毁伤概率增大。To deal with the vulnerable problem of UAV against mesoband electromagnetic pulse,taking the quad-rotor UAV as the research object,its structure and function are analyzed.The sensitivity of the receiver was analyzed by the electromagnetic sensitivity mechanism.The terminal response voltage with the load of 50Ωwas calculated by field-circuit coupling.The vulnerability calculation was carried out,and the relationship between field strength,repetition frequency and damage probability was obtained.The damage threshold under the action of three electromagnetic pulse sources was obtained by system-level effect test.Studies have shown that the components most vulnerable to interference and damage are receivers and GPS.As the re-frequency increases,the field strength threshold decreases and the probability of damage increases.
