【摘要】 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。更多还原

【Abstract】 The paper presents the results of the experimental research on HPM pulse compression at S band by the method of s witched energy storage. The input pulse is of the power ranged 1.0—2.7MW and 1. 4μs width. The width of output pulse is about 13—14ns, the power gain is ab out 40 and the output power is 106MW. A spontaneous gas breakdown switch is used . It is shown that the rise time of output pulse is dependent on the gas pressur e and gas ingredient and the power gain is of no relation with the rise time of output pulse.更多还原
