- When the modified kurtosis is maximized, the estimate of the range shift is obtained. 分析表明该算法具有良好的抗闪烁性能和抗噪性能。
- Then, the amount of the range shift between two echoes is searched by using the modified kurtosis as the alignment measure. 当两回波和包络的修正峰度达到最大时,以此时的距离偏移量进行补偿,就可将回波对齐。
- Relationship between concentration of active components in impregnating liquor and that in final catalyst product in preparation of Co Mo based wide temperature range shift catalyst was investigated. 本文探讨了钴钼系宽温变换催化剂生产中浸渍液活性组分浓度和成品中活性组分含量之间的关系。 催化剂的主催化成分、助催化成分及其助剂的含量大小是影响催化剂性能的重要因素 ,因此探讨浸渍法生产中浸渍液活性组分浓度和成品中活性组分含量之间的关系十分必要 ,也是可控制的。
- By introducing a range shift factor and a range scaling factor in range direction, a wavenumber domain imaging algorithm with completing registration during the course of imaging is presented. 通过在距离向引入距离平移因子和距离缩放因子,得到在成像过程中完成配准的波数域成像算法。
- Results show that the range alignment algorithm based on maximum modified kurtosis can estimate range shifts and fulfills range alignment. 结果表明,基于最大修正峰度的距离对准算法可以准确地估计出回波的距离偏移量,实现距离对准。
