| 摘 要： | 基于相对论返波管振荡器,提出了一种小信号牵引相位控制的方法,通过外加小信号对振荡器起振过程的引导,实现对输出微波的相位控制。相比于传统的方法,该方法可以利用ns量级的脉冲在较宽的带宽和较低的注入功率下实现对高功率微波振荡器的相位控制。在X波段相对论返波管振荡器相位控制实验中,利用百kW级的小信号,实现了对GW级高功率微波的输出相位控制,相位抖动小于±15°。

| Abstract: | Frequency locking and phase locking is the key issue for the research of high power microwave combination. An initial phase inducing method for high power microwave oscillator is put forward and investigated. The phase locking can be achieved in the condition of a wider frequency detuning and a lower power input by using this new approach. The phase of GW level high power microwave is controlled with jitter less than 15 by a weak signal with an injection power ration less than -40 dB and a pulse width of about 10 ns. The method can be extended to other types of high power oscillator such as relativistic magnetron, transition-time oscillator, Cherenkov radiation oscillator and so on. |
