Design of Missile Electrical System in High Power Microwave Environment

During the flight of guided missiles, it is susceptible to the influence of high power microwave irradiation, which will generate inductive electric field and affect the signal transmission inside the missiles. In this paper, CST software is used to establish the missile model and electrical model inside the missile, and the influence of electrical design on its microwave effect characteristics is studied. The simulation results show that the interference of high-power microwave on missile electrical signal transmission can be effectively suppressed by using shielded twisted pair, adding filter circuit and reducing the gap width between cabin sections. According to the results of simulation analysis, it provides guidance for the design of missiles electrical system in high-power microwave environment.
