摘要
本文对频率分析的几种主要方法进行了研究,比较了传统谱分析与现代谱分析的优缺点,同时利用最大熵谱分析与最大似然谱分析的关系解决了振幅恢复问题,最后给出了划分地震旋回的时间谱剖面的处理和分析方法。
<ABSTRACT>: Several main methods of frequency analysis are studided,advantages and disad-vantages of classic spectral analysis and modern spectral analysis is compared and the rela-tionship between maximum entropy spectrum analysis and maximum likelihood spectrum analysis is used to solve amplitude recovery in this paper. Last,process and analysis method of time spectrum profile for dividing seismic cycles is given.
