摘要

在传统匹配追踪算法的基础上,提出了一种改进的匹配追踪算法。引入了一种新的完整库构建策略,将Ricker小波作为原子,利用原始地震资料的最大相关系数估计完整库的位置和原子能。该方法进一步提高了分解精度,大大提高了算法的适应性。为了避免原子间距过小,引入了最小原子间距,进一步提高了分解效率和质量。模型试验和实际数据的应用表明,通过该算法不仅提高了信号稀疏表示的质量,加快了收敛速度,而且增强了算法的适应性和分解精度。该方法可以更好地获得有效的地震信息,提高地震解释的精度。

RESEARCH AND APPLICATION OF IMPROVED HIGH PRECISION MATCHING PURSUIT METHOD

Based on conventional matching pursuit (MP) algorithm, an improved approach of MP is presented in this paper. By introducing a new strategy of building complete library, the Ricker wavelet was taken as atoms and the maximum correlation of original seismic data was used to estimate the location and atomic energy of complete library. The decomposition precision was increased further through the method so that the adaptability of the algorithm was greatly improved. To avoid the atomic spacing being too small, the smallest atomic spacing was introduced, so the decomposition efficiency and quality were further improved. Model trial and application of practical data showed that not only the quality of the signal sparse representation through the algorithm was improved and the convergence speed was accelerated, but also the adaptability and decomposition precision of the algorithm were enhanced. Effective seismic information can be obtained better and the precision of seismic interpretation can be improved by the method.
