最大熵谱分析是一种具有较高分辨率的谱分析方法, 本文从三个方面对最大熵谱分析中的Burg算法和Marple算法进行了比较, 首先是对初相位的依赖性, 其次是频率分辨, 第三是抗干扰能力。通过这三个方面的比较, 进一步搞清了这两种算法的优缺点, Marple算法在抗干扰方面略逊于Burg算法, 而在其他两个方面优于Burg算法。

The maximum entropy spectrum analysis is a kind of relatively high resolution spectrum analysis method. We compare the Burg algorithm with the Marple algorithm in three aspects. The first aspect isthe dependance on the initial phase, the second is the frequency resolving power, the third is the anti-disturbance ability. Through the comparison in these three aspects, we further make clear the merit anddrawback of these two algorithms. The Marple algorithm is slightly inferior to the Burg algorithm in the anti-disturbance aspect, but better than the Burg algorithm in the other two aspects.
