Research on HEMP injection and radiation effect effect of EED

High-altitude nuclear electromagnetic pulse (HEMP) will lead to EED misoperation (such as early burst) or degradation of the performance and reliability (such as failure) etc. This paper is mainly about injection effect test and radiation effect test of high-altitude EMP on EED, tests are performed in typical HEMP environments. On this basis, researched and analyzed HEMP effect on EED. Analysis showed that ignition energy of HEMP on EED is related with the DC ignition sensitivity of EED; the more insensitive EED is, the bigger ignition energy is. EED is seriously affected, in HEMP environment that is the rise time is getting shorter.
