Abstract

Electromagnetic Pulse(EMP) has steep front in the time domain,but with short duration.In the frequency domain,EMP covers a wide frequency band.The general EMP is produced by the nuclear explosion or the non nuclear EPB(High-power Microwave Bomb).The EMP can radiate very high energy in a short time,which causes great threat to devices and systems which depend on the electronic devices.In this paper,the theoretical calculation numerical simulation and experiments are done to study the strong electromagnetic pulse environment.

First ,In this paper, the background of electromagnetic pulse technology is reviewed,and the importance of electromagnetic pulse testing technology is expounded by the development of modern electromagnetic pulse weapon.According to the research of the mature electromagnetic pulse testing technology,design and research of test system of electric field produced with EMP have been done.

    Secondly,theoretical study on the environment of strong electromagnetic pulse is completed and numeric analysis and theoretical arithmetic has been done.Protection of electronic system from EMP and test antenna technology is studied.A method to broad working band of EMP text system by simple antenna is raised.

    Finally,numerical simulation ,optimization and design have been done with HFSS.The value of text antenna which suit the strong electromagnetic pulse environment and a sheet of center frequency between 0.1GHz-1GHz of whip antenna are proposed .strong electromagnetic pulse environment test system has been designed and set up.Reliability of the text system in this paper is verified by practical application 

    In this paper,a text system of strong electromagnetic pulse environment and a method to design and text antenna are proposed,which do some help to the text of strong electromagnetic pulse environment HFSS强电磁脉冲测试天线的研究:/tongxin/lunwen_50136.html
