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

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．
