The Continuous Wavelet Transform Analysis of CPT(R) Logs

Due to the very high resolution of the CPT(R) measurements, the resulting data contain the information that can be analysed in terms of spatial frequency. One of the suitable tools for such analysis is the continuous wavelet transform (CWT). This method has considerable advantages over the traditional Fourier analysis, when applied to the limited duration time-series. The paper presents a case study of application of the continuous wavelet transform (CWT) method to emphasise the spatial frequency information, contained in the results of CPT(R) measurements from a survey site, located on the fluvial deposits. A brief outline of the method is presented. To illustrate the application, an example of CWT analysis carried out on a set of the CPT(R) logs is shown, together with original data and computational parameters. The resulting scalograms depict the frequency spectrum of the data.
