【摘要】 对裸露炸药在封闭空间爆炸过程产生的电磁辐射进行了实验研究,对现象产生的基本原理进行了分析。结果表明,典型炸药在封闭空间内爆炸产生的电磁辐射信号的持续时间为微秒量级,主要频率在100 MHz以内,起爆器放电和炸药爆炸产生的电磁辐射信号的持续时间和频率特性有明显不同。炸药爆炸产生的电磁辐射信号特征受炸药封装形式、实验场地的影响。更多还原

【Abstract】 In this paper,the electromagnetic radiation which is aroused by the explosives detonation in the close space has been studied,and the fundamental principle of the problem has been analyzed.It is shown that the duration time of electromagnetic radiation signal aroused by the typical explosives detonation in the close space is μs level,the frequency is less than 100 MHz,and there is obvious difference in the frequency character between the discharging of the detonator initiator and the explosive detonation.In the same time,the electromagnetic radiation is affected by the experiment field and the packing forms of the explosives.更多还原
