摘要
本文通过对目前常用的现代谱估计方法——最大熵谱估计方法中的谱峰幅度和谱线分辨率两个基本问题的分析和讨论,和经典的傅立叶谱估计方法作比较,指出在最大熵谱估计方法的应用中应注意的几个问题。
This paper analyzed and discussed spectral peak and resolut ion of maximum entropy Spectral estimation that are two essential problems of modern Spectral estimation. By comparison with classical Fourier Spectral estimmtion, the paper demonstrated several aspects which must be noticed in app lication of maximum entropy estimation methods.
