摘要
在文献[3]的基础上从数据处理方法上着手改进,采用逼近程度好,外推能力和唯一性强的趋势面残差叠加法进行数据的网格化,进而采用等值线追踪方法进行线性插值,从而绘制出较满意的雷基图,并使测绘时间缩短为原有的三分之一左右。
Load pulling effect is one the basic characteristics of microwaveoscillators,Contour lines of power and frequency of microwave oscillators are drawn onthe Smith chart to express the load performance.Rieke diagram provides the parametersfor designers in application of microwave tubes.In this paper,the methods of data processing and contour lines drawing of Rieke dia-gram are improved.The methods of trend surface added by margin,tracing contour linesand linear interpolation are chosen.With these methods,a fine Rieke diagram is drawn,and the drawing time is reduced greatly.
