    Resolution enhancement of seismic data via Burg maximum entropy prediction and temporal-frequency analysis

    • 摘要: 提出了一种提高地震资料分辨率的综合处理方法,即首先使用最大熵伯格预测方法来拓宽频谱,压缩子波的旁瓣,然后采用时频分析方法来重构高分辨率信号。实际资料的验证说明,该方法能有效提高地震记录的分辨率.

       

      Abstract: An integrated technique for resolution enhancement of seismic data is presented in this paper. The technique consists of two steps. First, Burg maximum entropy prediction is used to spread the spectra of the data and to suppress side lobes. Then, high-resolution signals are reconstructed via temporal-frequency analysis. Tests on real data show that the technique is effective in improving the resolution of the data.
