实验目的：

研究上课所讲谱分析方法，利用实验验证书中的结论，掌握各种谱分析方法，学会实验设计和实验结果分析。

实验内容：

所应用到的谱分析方法，包括：

1）　　非参数化方法：周期图（直接法）、BT法（间接法），Welch平均周期图法

2）　　参数化方法： RELAX、Capon

3）　　空间谱估计：常见的DOA方法（Capon）

-Experimental Objective: To study methods of spectral analysis class talking about the use of experimental verification of the conclusions of the book, to master a variety of spectral analysis methods, learn experimental design and experimental results. Experiment content: applied to the spectral analysis methods, including: 1) non-parametric methods: periodogram (direct method), BT method (indirect method), Welch average periodogram 2) parameterization: RELAX, Capon 3) spatial spectrum estimation: common of DOA method (Capon)
