摘　　要：用GW级超宽带电磁脉冲辐射装置实验研究了某电子系统的辐照效应,分析了开、关门状态下设备内04、08号分系统各检测点及接收天线在不同方位时02号分系统检测点上的响应特性,结果表明:在场强E=20kV/m的超宽带源(上升时间0.3ns,脉宽3～4ns)辐照时,开门时电路上及天线最佳耦合状态下设备02分系统电路上的响应的电压均可达1.6kV;开、关门时设备响应的带宽均为0～500MHz,主频约70MHz。The experiment on radiation ettect to a complicated electronic system by using GW ultra-wide band （UWB） radiation source was carried out. In cases of opening or closing the door of equipment under test （EUT）, the responses of test points on subsystems No. 04 and No. 08 of EUT were measured. The response characteristics of test points on subsystem No. 02 were tested at different orientations of antenna of EUT. And spectrum analysis was performed for response waveforms. The results show that the response voltage on internal circuits of EUT may reach about 1.6 kV at the condition of opening door of EUT when radiated by UWB source with 2.0 104 V/m of field strength （ rise time is 0. 3 ns and pulse width is 3-4 ns）. The maximum response voltage on subsystem No. 02 is about 1. 6 kV under the condition of optimum coupling of antenna. The response band width of EUT is about 500 MHz and main frequency point of response is about 70 MHz.
