Abstract: High repetition rate EMP simulator is a high-power radiation source, but it produces a very strong electromagnetic interference(EMI) while in operation. To combat this interference, an electromagnetic protection scheme based on DSP control, combining hardware protection with software reinforcement, was proposed. A bounded-wave simulator system was used to prove the feasibility of the scheme. The experimental results show that the DSP system using hardware shield and software reinforcement technology can work well near the EMP simulator, and that it is feasible and has strong anti-jamming capacity.

Key words: high repetition rate EMP simulator, DSP, hardware shield, software reinforcement
