高功率电磁脉冲干扰甚至损毁无人飞行器是应对小型无人飞行器威胁的一种非常有效的办法，高功率电磁脉冲对无人机系统进行干扰和毁伤主要通过前门耦合和后门耦合的方式。完成了高功率电磁脉冲对无人飞行器的毁伤破坏实验，完成了无人机在电磁脉冲源毁伤作用下的目标易损性分析，根据毁伤效果将高频电磁脉冲对无人飞行器毁伤等级分为三级，即干扰级、毁伤级、失效级。分析了电磁脉冲作用的主要目标元件，结果表明，无人飞行器最有可能受干扰的部分为接收机和电子调速器。在相关研究和实际应用时，应着重研究电磁脉冲对无人飞行器的接收机和电子调速器的毁伤破坏，根据接收机和电子调速器内部的电路结构来确定毁伤最佳频率。

High power electromagnetic pulse interference and even destruction of unmanned aerial vehicles is a very effective way to deal with the threat of small unmanned aerial vehicles (UAVs).The interference and damage of high power electromagnetic pulse to UAV system is mainly through the way of front door coupling and back door coupling. In this study, the damage of UAVs by high power electromagnetic pulse are analyzed, and the target vulnerability of UAVs under the electromagnetic pulse source is analyzed. According to the damage effect, the damage level of the high frequency electromagnetic pulse to UAVs is divided into three levels, namely the interference level, the damage level and the failure level, and the main targets of electromagnetic pulse are analyzed. The results show that the most vulnerable parts of the UAVs are the receiver and the electronic governor. Therefore, in future research and practical application, it is necessary to study the damage and destruction of the electromagnetic pulse to the receiver and the electronic governor. And the optimum frequency of damage should be determined based on the circuit configurations of the receiver and the electronic governor.
