Finally , some methods of digital processing techniques , such as polynomial curve fitting and exponential curve fitting and subsection curve fitting , are used firstly to compensate the performance of the detector . the measurement accuracy of the reader is improved , with the validity proved 首次運用了多項式曲線擬合技術(shù)、指數(shù)曲線擬合技術(shù)以及采用分段擬合的技術(shù),補償檢波器的性能,提高了通信系統(tǒng)的測量精度,應(yīng)用效果顯著。
The antenna gain , directivity and reflection coefficient are calculated via finite element method in hfss . spline interpolation and polynomial curve fitting are applied to construct diagrams illustrating the capsulation characteristics . some general conclusions of interest are obtained 探討了各個封裝參數(shù)對輸入端反射系數(shù)、方向性系數(shù)、效率和增益等性能指標(biāo)的影響,得到一些規(guī)律性結(jié)論,為射頻振子天線的封裝應(yīng)用提供了參考性的建議,并指出了進(jìn)一步研究的方向。
