通过工质爆燃,产生了具有很宽频谱的电磁辐射。用4个宽带天线从不同方向对球形工质产生的电磁辐射进行了接收测量,并对信号作了频谱分析。实验结果表明:150 g工质爆炸产生的电磁脉冲持续时间为50 ns,上升沿很陡,频谱连续,频率范围为1~4 GHz,峰值频率为2 GHz,功率为2 W。对爆燃型工质产生电磁辐射的机理进行了初步理论探讨,认为等离子体辐射可能是产生电磁辐射的源。
Deflagration through the working fluid, resulting in a wide spectrum of electromagnetic radiation. Four broadband antennas were used to measure the electromagnetic radiation generated by spherical working fluid in different directions and the frequency spectrum was analyzed. The experimental results show that the duration of the electromagnetic pulse produced by the 150 g working fluid explosion is 50 ns, the rising edge is steep, the frequency spectrum is continuous, the frequency range is 1 ~ 4 GHz, the peak frequency is 2 GHz and the power is 2 W. The mechanism of the electromagnetic radiation generated by deflagration working medium is discussed theoretically. It is considered that the plasma radiation may be the source of electromagnetic radiation.
