摘要
为了得出超宽谱电磁脉冲脉宽对无线电引信的影响与作用机理,选择某型集成电路米波无线电近炸引信,给出了研究所需的试验设备和试验方法,通过变换超宽谱脉宽对无线电引信进行辐照,得出了脉宽变化对无线电引信的影响,并确定了被试无线电引信在不同脉宽下的发火阈值.最终得出超宽谱电磁脉冲与无线电引信的作用主要是通过"后门"的方式耦合进入的.超宽谱电磁脉冲脉宽的变化对引信有很大的影响,超宽谱脉宽越窄,对引信的影响越大.

Abstract:
In order to get the coupler mechanism between the radio f uzes and changes of the ulta band spectra elect romagnetic pulse,choosing a kind of fuzes whose wavelengt his about 1 meter has been selected.The methods and equip ment of the experiment have been int roduced in our instit ute.In the experiment,the width of ulta band spect raelect romagnetic pulse is changed,according to the results of the experiment,the influence to the fuzes while width of pulse is changed is analysised.The threshold value while the fuze is exploded is ascertain in the condition of changing width of pulse.At last,conclusion is got that impactbetween ulta band spectra elect romagnetic pulse and fuzes is through the passage of "back door".The changes of width of pulse affect fuzes greatly.The narrower width,the greater influence.
