一种改善相关子波特征的扫描信号——“旋转相位,对数分段”扫描信号

Zhang Hongle. Rotation phase and logarithm fragment signal - a kind of sweep signal for improving signature of correlated wavelet.

可控震源施工扫描信号要有尽可能小的相关子波边叶,本文由分析信号及信号相关子波的特性,得出“旋转相位,对数分段”扫描信号符合这一要求。通过进一步的分析、论证得出“旋转相位,对数分段”扫描信号确实是一种能改善相关子波特征的扫描信号。

The edge of sweep signal’s correlated wavelet should be as small as possible. After making an analysis of features of signal and its correlated wavelet . the author find out that the sweep signal after rotation phase and logarithm fragment is suitable. Through further study and test, this sweep signal really can be useful for improving signature of correlated wavelet.
