Abstract：In order to explore the coupling mechanism and effect law about high power electromagnetic pulse attacking missiles，the representative waveform and spectrum of double exponent electromagnetic pulse is ana⁃lyzed.Based on the missile structure，coupling modes of high power electromagnetic pulse are discussed，and an model was constructed used CST.With the method of FDID，distribution of surface current and changing of elec⁃tric intensity inside was calculated.The special case was that electromagnetic pulse effect cables used in steering engine through wings and apertures of missile was analyzed.Lastly，the interference on homing system is analyzed qualitatively，and some protection measures was presented.The results show that the damage reason of part of missile is instantaneous energy from the electromagnetic pulse coupling inside through wings and apertures of missile.
