摘　　要：基于一套由脉冲电压发生器和GTEM室组成的模拟装置,对LEMP和NEMP进行了模拟。分别对这两种强电 磁脉冲进行了采集,结果表明通过调整模拟装置的参数,该装置既可以模拟LEMP环境,又可以模拟NEMP环境,在 GTEM室内一定区域能产生相对均匀的电磁脉冲场环境,可用于敏感器件的电磁敏感度实验。A method is introduced to simulate the strong EMP environment. The device is made up of a set of pulse voltage generator and a set of GTEM cell. The device can simulate LEMP and NEMP by changing ist parameters. To test the device, several kinds of lightning waveforms and NEMP are chosen to be simulated according to criteria. The valid testing method is used and the result is appropriate. The device can provide relative even electromagnetic pulse environment in some degree to test the susceptibility of sensitive device.
