摘要
本文基于 Bubble函数构造小波基，用 Mallat塔式快速算法对地震信号进行二维多分辨分析，并利用局部极值理论提取、检测反射同相轴及断层。理论和计算结果表明，该方法能够检测出不同尺度下的地震信号突变特征，且具有一定的抑制噪声能力。
This paper based on Bubble function construct wavelets and decompose seismic signals by using Mallat algorithm. According the theory of position extreme value, events and faults are detected. Both theory and result manifest this method can detect the information of sudden change in different scales seismic signals and reduce noise effectively.
