【摘要】 功率合成是获得高功率微波辐射的一条重要技术途径。它允许在单个高功率微波源的基础上将有效辐射功率提高n倍甚至几十倍，对高功率微波技术的发展具有深远的意义。目前，国际上对高功率微波功率合成报道不多；国内则未见报道。本文重点研究高功率合成的关键技术。对高功率微波功率合成的关键技术如锁相源、高功率移相器、功率合成器进行了讨论分析，结合实验室实际情况，提出了以三端口输出相对论磁控管作为相干高功率微波源进行高功率合成技术研究的方案。理论计算和三维电磁仿真软件HFSS结合，设计了一种高功率微波介质移相器和波导型功率合成器，给出具体设计参数。目前处于实际加工阶段。本文还用矩量法对一种锁相源—多注速调管的谐振腔参数进行了计算和仿真，结果与实测一致。对输入腔加载同轴滤波器也做了一些初步设计，理论计算和HFSS仿真吻合较好。更多还原

【Abstract】 Power combining technology is one of the important method which can obtain high power microwave radiation. It can enhance efficient radiation power to n times or more over based on the single high power microwave oscillator, so it’s meaningful to the development of HPM. There isn’t too much power combining reports of HPM at the present time in international. This thesis has studied some key HPM power combining technologies such as phase-locked source, high power phase shifter and high power combiner. According to the facts of HPRL, it presents a combining project of relativistic magnetron with three output ports which acts as an phase-coherent HPM source. Through theoretical computation and HFSS simulation, we have designed the HPM dielectric phase shifter and waveguide-based combiner. At the end, this thesis also has studied some characters of multiple-beam klystron resonator by moment method and the measured result accords with the computed result. A coaxial loaded filter of input resonator also presented in the thesis, the simulation data agrees well with the theoretical data.更多还原
