  In order to investigate characteristics of SBP (Subbottom Profiler) seismic data energy envelopes are obtained by using a CWT (Continuous Wavelet Transform) of raw data and Hilbert transform. In addition, energy envelopes which are obtained using a conventional band-pass filtering and low-pass filtering method are compared with those obtained by a CWT method. Energy envelope obtained by using a CWT method is pretty much similar to cubic spline curve which is constructed by connecting positive peaks of the raw data. Energy envelopes obtained by CWT method reflect energy distribution contained in the signals better than those obtained by conventional filtering method do.
