摘　　要：爆炸磁频率发生器是一种结构简单、小型化的电磁脉冲产生和辐射装置。为了优化其性能,从数学模型入手进行研究,得出输出信号所满足的Bessel函数,分析了在不同电参数下输出信号的模式及电路中的能量分配。研究结果表明,当电感变化到初始值的1/e所需时间与初始载波频率的乘积较大时,发生器的输出信号为振荡模式,且二者乘积越大,载波频率越高,对其辐射越有利。The explosive magnetic generator of frequency is a simple and small device for generating and radiating electromagnetic pulse. To optimize its performance, the mathematical model is researched first, and then the Bessel function which meets the output signal requirement is obtained. The output signal mode and the circuit energy distribution under different electrical parameter are analyzed. The research result shows that when the product of the time during which the inductance changes to 1/e of its initial value and initial carrier frequency is large enough, the output signal of the generator is the oscillation mode. The larger the product is, the higher the carrier frequency is and it is beneficial to the radiation.
