【摘要】 高阶统计量方法是研究非高斯过程,非线性系统和非最小相位信号的有力工具。一些使用相关函数或功率谱进行分析与处理而得不到满意结果的问题都可以使用高阶统计量方法。本文介绍了高阶统计量在地球物理学中的应用现状。更多还原

【Abstract】 Higher-order statistics is a useful tool for studying non-Gaussian processes,nonlinear systems and non-minimum phase systems.Some problems,which cannot be solved satisfactorily using power spectrum or correlation functions,can be worthy of using higher-order statistics method.In this paper,the main theoretical results about applications of high-order statistics in geophysics are summarized.更多还原
