建立了利用储能切换法实现微波脉冲压缩的实验装置并进行了实验研究。在输入脉冲功率为 2 .7MW,脉冲宽度为 1 .4 μs的情况下 ,脉冲压缩功率增益近 4 0 ,输出微波脉冲功率为 1 0 6MW,脉宽为 1 3～ 1 4 ns。实验结果表明输出功率增益与气压和气体成分没有明显的联系 ,气体击穿的分散性可能是导致输出功率增益波动的主要原因。
An experimental device for microwave pulse compression using energy storage switching method was established and experimentally studied. When the input pulse power is 2.7 MW and the pulse width is 1.4 μs, the pulse compression power gain is nearly 40, the output microwave pulse power is 106MW and the pulse width is 13 ~ 14 ns. Experimental results show that there is no obvious relationship between output power gain and gas pressure and gas composition. Dispersion of gas breakdown may be the main reason of fluctuation of output power gain.
