由于沉积覆盖层的横向不均匀性以及表面波的叠加造成的地震事件不明确,使用高分辨率地震工具调查岩溶地形的成功有限。针对这些问题,本文提出了一种基于地震反射数据的岩溶特征谱分析方法。首先,应用S变换抑制地滚波。作为一种时频变换,S变换提供了频率相关的分辨率,同时保持与傅立叶谱的直接关系。应用基于S变换的滤波器在时频域中衰减地滚波。然后,利用连续小波变换对潜在岩溶特征进行时频映射,表现为频率分异异常。综合模型和实际数据实例验证了谱分析方法在岩溶特征检测中的有效性。
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.
