【摘要】 行波管根据不同的慢波结构,主要可以分为螺旋线行波管和耦合腔行波管。螺旋线行波管具有频带宽、效率较高和重量轻等一系列的优点,一直备受各种电子系统青睐。由于毫米波螺旋线行波管具有带宽宽、效率高和体积小的特点,可以大量的进行功率合成使用,也就成为了毫米波相控阵雷达优先选择的器件。本文将基于毫米波螺旋线行波管现有的设计、制造和测试平台,重点针对毫米波螺旋线行波管的电子光学系统、色散和耦合阻抗仿真及在线测量、注波互作用计算及样管验证结果等进行研究,在理论分析的基础上,采用CAD软件进行模拟仿真计算,通过试验验证的方法来寻求解决问题的方法,最终研制出符合指标要求的毫米波螺旋线行波管。本论文的研究工作和创新点如下:1.利用MTSS、TAU、CST、MAXWELL、ANSYS等软件设计并优化电子枪电子光学系统、注波互作用、输能系统、磁系统和收集极等部件,得到满足指标要求的整管方案。2.从理论分析螺旋线跳变技术的作用,运用MTSS软件来模拟螺旋线衰减量的大小、螺距设置、螺距跳变方式和衰减器的位置对输出功率的影响。3.优化设计完成后,利用在线测量技术,对慢波系统的色散、耦合阻抗进行在线测量,验证慢波系统的色散、耦合阻抗是否与设计值有较高的符合性,通过反复的设计、验证,可以在不装配整管的情况下,完成慢波系统的设计验证。4.研究了毫米波行波管的相位一致性测量和补偿技术,并完成了实测。5.通过本文的研究,本人结合实际工作情况,总结了一点工作体会。更多还原

【Abstract】 According to different slow wave structure, the traveling wave tube can be divided into the helix traveling wave tube and the coupled cavity traveling wave tube. Helix traveling wave tube has a series of advantages, such as wide band, high efficiency and light weight, etc., has been favored by all kinds of electronic systems. The millimeter wave helix traveling wave tube with wide bandwidth, high efficiency and small volume features, can be a lot of using synthetic power, has become the preferred choice of millimeter wave phased array radar devices.In this paper, the design, fabrication and test platform of the millimeter wave helix traveling wave tube are studied. The electronic optical system, dispersion and coupling impedance simulation and on-line measurement of the wave, dispersion and coupling impedance are studied. On the basis of theoretical analysis, the CAD software is used to carry out the simulation calculation, and the method to solve the problem is solved by the method of testing. We find a solution to the problem, and ultimately manufacture in line with the index requirement of millimeter wave helix TWT.The research work and innovation points of this paper are as follows:1. By using MTSS, TAU, CST, MAXWELL, ANSYS software to design and optimize components, such as the electron gun, beam wave interaction, transmission system, magnet system and collector, we finally get to meet the index requirements of tube scheme.2. We analyze the role of helix jump technique in theory, by using MTSS to simulate the influence of size of attenuation, distance setting, jump way and attenuator location on output power.3. After design, we use online measuring technique for on-line measurement of dispersion and coupling impedance, try to find out whether dispersion and coupling impedance is consistent with design. Through repeated design, test and verify, we can finish the design of slow wave system in the circumstances without installing tube.4. The study of the phase consistency measurement and compensation technology of millimeter wave traveling wave tube, and complete the test.5. Through the paper, I combined with the actual work situation, summed up a littlework experience.更多还原
