摘　　要：介绍了用不同于常规炸药的工质爆炸可以产生具有很宽频谱的电磁辐射。用四个宽带天线对球形工质产生电磁辐射从不同方向进行了接收测量,并对信号作了频谱分析。此外,对爆燃型工质产生电磁辐射的机理进行了理论探讨。A wideband spectrum electromagnetic radiation from the explosive which is different from conventional high explosive. Four broadband antennas are employed to observe shock-induced electro- magnetic radiation from a spherical explosive. The frequency spectrum from these experiments is analyzed using time/frequency Fourier methods. And the radiation mechanism of the phenomenon is discussed theoretically.
