| 摘要: |
| 介绍了一种先利用初级源进行小功率合成产生微波波段拍波，然后再用单只行波管放大器进行功率放大产生较高功率微波波段拍波脉冲的方法，目的在于为高功率微波效应研究提供方便、实用的拍波效应源。实验结果显示：利用单只行波管放大器可以在微波波段产生拍频为1MHz～几百MHz的拍波，并可以调节两个频率分量在总输出中的功率比例，实验获取的拍波脉冲输出功率为2kW，脉冲重复频率为10kHz。实践证明，这种方法可以满足部分高功率微波拍波效应研究的需要，有一定的推广应用价值。 |

| Abstract: |
| We present in this paper the production of beat wave using a single L-band travelling-wave tube (TWT) amplifier. The beat wave was first generated in a primary source using power synthesis method, then injected into a TWT amplifier to obtain relatively high power output. This approach is initiated to provide practical beat wave radiant source for high power microwave (HPM) effect research. Experimental results demonstrate that for 1～2GHz carrier frequency, it is quite practical to produce beat frequency ranges from 1MHz to 900MHz at 10kHz repetitive rate using one TWT amplifier. The output parameters of the beat wave are readily adjustable in terms of varying the feeding frequency components' power levels. The production of beat wave using single TWT amplifier takes advantages over some conventional methods since the beat wave can be formed in low power, low cost microwave sources. This method has been successfully used in certain electrical system HPM vulnerability effect experiments. |
