【摘要】 炸药爆炸过程产生的电磁辐射在很多领域引起了人们的重视。为了获得典型炸药爆炸过程产生的电磁辐射特性,利用天线测量系统对炸药爆炸过程的电磁辐射特性进行了实验研究。结果表明:炸药爆炸产生的电磁辐射信号强度与炸药当量的1/3次方成正比,随距离增加而衰减。几种典型炸药的爆炸电磁辐射信号主要频率在100 MHz以内,同一种炸药信号频谱特征与当量、爆心距无关,不同种类炸药产生信号频谱不同。更多还原

【Abstract】 The electromagnetic radiation in explosion has been become a research hot spot in many fields.To obtain the electromagnetic radiation characteristics of the explosion of typical explosives,the antenna measuring system is utilized in explosion experiments. The results show that the signal intensity of electromagnetic radiation generated by explosion is in direct proportion to the cube root of the explosive equivalent,and decreases with the increase in the explosive distance. The major frequency components of the electromagnetic radiation signal from several kinds of typical explosives are below 100 MHz. The frequency spectrum of signals from the same explosive is independent of the equivalent and distance. The frequency spectrums of signals from various explosives are different.更多还原
