The Research On Complex Electromagnetic Field Interfereing The Airborne Equipment

Wide range of applications and development of electronic equipment，resulting inincreasing the energy of electromagnetic radiation in the surrounding space. The airborneplatform due to the high density of electronic devices, high-sensitivity characteristics, isvulnerable to the interference of the external radiation field，and has been a difficult issue inengineering area.A detailed analysis of the airborne equipment may be encountered in complexelectromagnetic environments and electromagnetic environmental effects is made of in thispaper, and also the integrated field strength on the environment, the formation mechanismand calculation methods were analyzed. Analysis of the anti-jamming performance ofairborne equipment through complex electromagnetic environment are carried out, inaccordance with the two ways of the space radiation field coupling into the aircraft——thefront door coupling through antenna coupled into and the back door coupling through thehole or sewn into. With use of the amount of law and a fast multi-level sub-algorithm, wecalculate out the coupling current in aircraft antenna between the external radiation field, thenachieve the amount of jammed from the antenna to wireless devices, Compared with thesafety value of antijamming，make a budget estimation.Finally, the overall structure of the simulation software, data flow diagrams and softwareinterface demo are proposed.
