摘要
本文通过研究地震信号小波变换模特征点的变化规律和特征 ,揭示了地震奇异点和其小波变换模极值的关系。通过研究这些关系 ,对小波各级分解的模特征点进行变频域处理 ,这样使求解李氏指数的非线性最小二乘解较稳定可靠。
By studying changing rule and character of modular characteristic points of wavelet transform of seismic signal,the paper revealed the relations between seismic singularity and extreme of module of wavelet transform. The modular characteristic points of all level of wavelet decomposition have been processed by the studying results of these relations,obtaining a stable and reliable non linear least square solution of Lipschitz index.Good results are obtained either from the examination of synthetic model or from the processing of real field data.
