Electromagnetic pulse effect analysis for the radar system

The ability of the radar system against electromagnetic interference is determined,and the type and interference degree of the typical electromagnetic wave are introduced.In order to explore the electromagnetic pulse's effect on the electronic device,the experiments on LM324N and CD4069UB with the square-wave pulse of different width are done,in which it is found that the device circuit's damageis related to the magnitude of pulse energy to a great extent,and there is a phase from adiabatic course to thermal-balance course.The effect of the adiabatic burning on the electronic device caused by the electromagnetic pulse is verified.The electromagnetic protection principle is proposed.
