| The strong electromagnetic pulse generated by the high power electromagnetic can radiate target with high amplitude, resulting in the target electronic system failure. With the development of microelectronics technology, large-scale and ultra large scale integrated circuit has been widely used in various electronic devices, whose performance has also been improved. However, they become more sensitivity and vulnerability. The electromagnetic environment is worsening and the demanding of the electromagnetic interference environment is increasing, which result the electromagnetic pulse damage and protective technology research have been paid more and more attention.In recent years, with the militarization and arms race in space increasingly fierce, space anti-satellite warfare has become one of the most effective ways to seize space. Deteriorating electromagnetic environment and the increasing demand of interference electromagnetic environment, make the strong electromagnetic pulse damage capacity to the satellite system and protection technology research more and more reality and urgency.In this paper, the main research contents are following. Firstly, design an electromagnetic pulse bomb, and then analyze its signal characteristics and killing ability. Secondly, analyze the vulnerability of the satellite receiver system, and then establish damage criteria. Thirdly, design three bands of typical antenna, such as yagi, four arm spiral and horn, and establish mathematical model, and then give the simulation algorithm based on FDTD method. Forth, the influence of different width, incident angle and field strength on three kinds of band antenna and band cavity with coaxial are simulated and researched, then maximum damage distance and power density are obtained, the simulation results coincide with the MOM method. Finally, based on the above research results, take corresponding measures to improve anti-electromagnetic interference ability of the satellite receiver system. |
