摘要
本文利用小波技术中的Ｍａｌａｔ算法进行奇异性检测，以确定地震记录的突变点。采用小波函数模拟初始子波，并通过极大似然估计优化子波和反射系数，再由反射系数推算波阻抗界面。最后，用理论模型和地震数据进行了数值计算，效果很好。
This paper makes singularity detection by using Mallat algorithm from small wave technology to identify catastrophe point of seismic record. Small wave function is used to simulate initial wavelet. Wavelet and reflection factor are optimized through maximal possibility estimation. Then the interface of wave impedence inversion is calculated from the reflection factor. At last, numerical calculation is made by using theoretical model and seismic model, and good result is obtained.
