Beschreibung
Zusammenfassung:	The invention discloses a signal processing method for improving the detection precision and range of tube wave method pile bottom karst, and the method comprises the steps: separating and extracting three characteristic parameters (instantaneous amplitude, instantaneous phase and instantaneous frequency) of a signal through Hilbert transform, and carrying out the analysis and interpretation of a tube wave signal from the three dimensions of amplitude, phase and frequency. 本发明公开了一种提高管波法桩底岩溶探测精度与范围的信号处理方法，本发明通过希尔伯特变换将信号的三个特征参数(瞬时振幅、瞬时相位和瞬时频率)分离并提取，从振幅、相位和频率三个维度进行管波信号的分析与解译。
