| Abstract: | Electromagnetic pulse causes serious threat by coupling with high energy into the radar system through the antenna,cable,gaps and so on.In this paper,the damage mechanism of electromagnetic pulse to radar through ＂front door＂ couple is analyzed,the antenna coupling formula of radars is given,and the interference effects on radar receiving system by EMP are simulated with ADS software.The measures of anti-EMP are proposed in the end. |

| Keywords: | intense electromagnetic pulse coupling front-door back-door |
