摘要
高阶统计量方法是研究非高斯过程,非最小相位信号和非线性系统的有力工具,其应用领域已涉及通信、地球物理、生物医学、故障诊断等.本文就近年来高阶统计量在地震勘探中的应用现状进行简要的综述,并根据高阶统计量在相关领域的应用特点展望了它在地球物理领域的应用前景.
Highorder statistics is a useful tool for studying nonGaussian processes, nonminimum phase systems and nonlinear systems. The method of highorder statistics has been applicated widely in different fields such as Communication, Geophysics, Biomedical, Fault Diagnosis etc. This paper summarizes the main theoretical results about applications of highorder statistics in seismic exploration, and put forward its prospect on geophysics field in the future.
