| The main work of this paper is interference signals simulation system based on a certain type of missile. This paper introduces the type missile weapon system electromagnetic compatibility properties, describes the composition of complex electromagnetic environment at the launch site and electromagnetic interference on the dangers of space launch. Analyzes the simulation characteristics of electromagnetic interference in the complex environment.In order to make the system can adapt to the launch complex electromagnetic environment needs, This paper carefully analyzes a certain type of missile weapon system of each equipment, systems of electromagnetic interference principle and characteristics, analyzed the vulnerable spot of electromagnetic interference protection. In order to make the simulation process jamming signal feature more real, the characteristics of EMI at the launch site were analyzed.According to comprehensive electromagnetic environment at launch and complicated characteristics of EMC at the certain type missile, this paper analyzes the features of interference sources, coupling path and sensitive equipment on complex electromagnetic environment, discusses the rule of EMI simulation modeling. Finally, EMI simulation model has been designed. This model can realize the following functions, such as jamming signal acquisition, signal modulation amplification and jamming signal injected. Simulation proves that the system is effective for single waveform and low-frequency waves. |
