您要查找的是不是:
- When the modified kurtosis is maximized, the estimate of the range shift is obtained. 分析表明該算法具有良好的抗閃爍性能和抗噪性能。
- Then, the amount of the range shift between two echoes is searched by using the modified kurtosis as the alignment measure. 當兩回波和包絡的修正峰度達到最大時,以此時的距離偏移量進行補償,就可將回波對齊。
- 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. 本文探討了鈷鉬系寬溫變換催化劑生產中浸漬液活性組分濃度和成品中活性組分含量之間的關系。 催化劑的主催化成分、助催化成分及其助劑的含量大小是影響催化劑性能的重要因素 ,因此探討浸漬法生產中浸漬液活性組分濃度和成品中活性組分含量之間的關系十分必要 ,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. 通過在距離向引入距離平移因子和距離縮放因子,得到在成像過程中完成配準的波數域成像算法。
- Results show that the range alignment algorithm based on maximum modified kurtosis can estimate range shifts and fulfills range alignment. 結果表明,基于最大修正峰度的距離對準算法可以準確地估計出回波的距離偏移量,實現距離對準。
