通过对国内外瞬时多脉冲产生技术的调研,结合超宽谱脉冲的特点,开展了三种瞬时超宽谱多脉冲产生技术研究。脉冲分割方式由于需要多个开关,而每个开关都存在一定的导通电感和导通电阻,会导致被分割的脉冲前沿变缓,同时幅度变小;形成线串联方式虽然存在开关电容、隔离电感等的影响,但通过优化获得了较稳定的双脉冲输出;多脉冲合成方式利用磁性材料的特殊性能来传输和隔离脉冲,但现有的一些磁性材料的响应速度不够,即在ns脉冲下,磁芯的工作点来不及变化,并未起到磁隔离的作用。
Through the investigation of transient multi-pulse generation technologies at home and abroad, combined with the characteristics of ultra-wide-band pulses, three kinds of instantaneous super-broad-spectrum multi-pulse generation technology are studied. Because of the need for multiple switches pulse division, and each switch has a certain on-resistance and on-resistance, will lead to the pulse edge is slowed down, while the amplitude becomes smaller; although the formation of a series of wire switched capacitor, isolated Inductance and so on, but the stable two-pulse output is obtained by optimization. The multi-pulse synthesis method utilizes the special properties of the magnetic material to transmit and isolate the pulse. However, some existing magnetic materials have not enough response speed, that is, under the ns pulse , Core work point too late to change, did not play the role of magnetic isolation.
