Research On Field-line Coupling Under The Complex Electromagnetic Environment

With the development of science and technology, electromagnetic environment isbecoming more and more complex in the future battlefield, research of externalelectromagnetic field on communication cable lines coupling response becomes moreand more importantThis paper focuses on the communication cable lines coupling is studied. The firstis the analysis of complex electromagnetic environment of communication cable, andthen to electromagnetic pulse for external source, based on distributed parametertransmission line theory, based on the Agrawal model were established for shieldingwire and a shield line lines coupling model, using MATLAB software and C++programming, completed the cable terminal lines coupling response simulationanalysis, reached with the reference comparison of the calculated results to verify thecorrectness of this method effect. Finally, from the angle of signal integrity analysis ofexternal electromagnetic pulse effect on cable, puts forward the related electroma gneticprotection measures, so as to the actual electromagnetic protection work has played acertain reference significance.
