提出了一种新型的基于圆柱谐振腔的高功率级波脉冲压缩系统,介绍了该系统的结构形式,给出了部分关键器件的数值模拟结果,对系统的功率容量及品质因数进行了初步分析.对于高功率微波(HPM)脉冲压缩系统来说,系统的功率容量与最终获取的HPM功率大小密切相关,谐振腔的固有品质因数与系统效率密不可分,工程实践表明,相对于基于矩形谐振腔的脉冲压缩系统,本文设计的基于圆柱谐振腔的脉冲压缩系统功率容量可提高一个量级,谐振腔的固有品质因数可提高5倍以上.
A new type of high-power pulse compressing system based on cylindrical cavity was proposed. The structure of the system was introduced. The numerical simulation results of some key components were given. The power capacity and quality factor of the system were preliminarily analyzed For the high power microwave (HPM) pulse compression system, the power capacity of the system is closely related to the final HPM power. The inherent quality factor of the resonator is closely related to the system efficiency. The engineering practice shows that, compared with the rectangular resonator , The pulse compression system based on cylindrical resonator designed in this paper can increase the power capacity by one order of magnitude and the inherent quality factor of the resonator can be increased more than 5 times.
