We derive the integral equation which expresses the S-transform ridge amplitudes in terms of Fourier amplitude spectrum of the reconstructed signal...

... on the assumption of white noise to the reflectivity, while the assumption is difficult to meet in practice. In fact we have found that in BoHai oilfield the amplitude spectrum of reflectivity for thin-interbed layers is a "blue spectrum", non "white spectrum", and this causes the extracted wavelet is inaccurate...
