摘要 J. P. 伯格(1967)提出的最大熵谱分析方法是一种改进的功率谱估算方法,它可以有效地提高功率谱的分辨率。但是,在设计预测误差滤波器的时候,如何正确地选择滤波器的长度仍是一个困难。本文用实例比较了几种确定滤波器长度的方法,认为J. G. Berryman提出的经验公式对于估算地震信息的功率谱是有效的。
Abstract:The maximum entropy spectrum analysis method presented by J.P. Burg in 1967 is an improved method far estimating power spectrum, which can effectively improve the resolution of a power spectrum. However, it remains difficult to choose correct filter operator length in designing a predictive error filter. Several methods far determining filter operator length having been compared by using actual examples, the empirical farmina presented by J.G. Berryman is considered effective in the estimation of power spectrum of seismic information.
