The use of high-resolution seismic tools to investigate karst terrain has had limited success due to the ambiguous seismic events caused by lateral heterogeneities of the sedimentary cover, as well as the superimposition of surface waves. To address these problems, a spectral analysis scheme is proposed on the seismic reflection data to characterize karst features in this paper. First, theS-transform is applied to suppress the ground roll. As a type of time–frequency transform, theS-transform provides frequency-dependent resolution while maintaining a direct relationship with the Fourier spectrum. Application of a filter based on theS-transform attenuates ground roll in a time–frequency domain. Then, the continuous wavelet transform is employed for the time–frequency mapping of potential karst features, which are featured as frequency differentiation anomalies. Synthetic model and real-data example validate the efficiency of the spectral analysis scheme for the detection of karst features.
