信号的突变性或奇异性通常携带有最重要的信息,小波变换为信号的多尺度瞬态分析提供了最合适的方法,本文阐述了基于小波变换模极大值的奇异信号检测理论,并将其应用在沉积岩层厚度探测信号的奇异性检测中,通过计算机语言编程,对实测信号奇异点进行定位,从而判断出沉积岩层的厚度,为沉积矿层厚度探测提供了一种新颖的方法。 Signal mutation or singularity usually carries the most important information. Wavelet transform provides the most suitable method for multiscale transient analysis of signals. In this paper, we introduce the theory of singular signal detection based on modulus maxima of wavelet transform, Its application in the detection of sedimentary strata thickness signal detection singularity, through computer programming language, the measured signal singular points to locate, and thus determine the thickness of sedimentary rock, sedimentary seam thickness detection provides a novel method.
