HPM effect analysis and modeling method for microwave components based on effect data

摘要: HPM对微波器件的输出脉冲影响主要有幅度变化、脉宽变化、相位变化以及暂时性压制，以此为基础建立了4种效应参量的模型，分别是衰减因子、脉宽、相移和压制时间。在建立效应参量模型时，参照分离变量法，提出使用加权函数的方法把多维函数分解成多个１维函数相乘，基本解决了利用有限实验数据建立数学模型的问题。给出了利用效应数据建立数学模型所常用的几种数据处理方法，如曲线拟合、查表／插值和概率统计，并给出了该方法在TR放电管效应评估中的使用实例。Abstract: In the experiments of high power microwave(HPM) effects on microwave components, four kinds of effect phenomenon were observed, including the changes of microwave pulse power, width, phase and transient HPM suppression. Based on these phenomena, mathematical models of four effect parameters were built. According to the variables separation method, the method of weighted function was brought forward and used in decomposing the multidimensional function. Results show that the way is effective on mathematic models, which were built of finite experimental data. In addition, several important means of data processing were introduced. Finally, the application of the new method to effective evaluation of TR tube was given．
