摘　　要：针对飞行器在复杂电磁环境下难以进行工作效能分析的问题,进行了某飞行器机体和控制导线在超宽带高功率微波(UW S-HPM)辐照下的效应及耦合实验研究.利用回输信号模拟器使实验具有重复性;采用改变控制导线的长度、辐照方位、辐照部位等措施,使实验具有普适性.研究结果表明:飞行器在超过25 kV/m场强的UW S-HPM辐照下,会受到干扰并使其坠毁;干扰能量的耦合机理是电磁脉冲通过控制导线进入控制箱,并影响控制指令的形成.在实验基础上,分析了干扰耦合与各种因素的关系,从而为装备电磁防护提供了理论依据.It is difficult to analyze the working capability of aircrafts under the complicated electromagnetic environment,so we experimentally studied the radiation and coupling effects of the UWS-HPM on the aircraft and its control-line.The feedback signal simulator was used to make the experiment repeatable.The control-line＇s length,irradiation azimuth and position were changed to make the experiment universal.The result shows that the aircraft produces interfering effects and makes itself prang under GT 25 kV/m field intensity environment.The interfering energy coupling mechanism is that the EMP enters control-box through control-line and influences the forming of control instruction.Based on the experiments,the relationship of coupling value of line terminal and varied factors was analyzed,which provides the theoretic basis for the equipments protection.
