中文说明： 用于建立主成分分析模型，仿真效率很高的，基于kaiser窗的双谱线插值FFT谐波分析，保证准确无误，是学习通信的好帮手，本科毕设要求参见标准测试模型，有均匀线阵的CRB曲线。
English Description：
For a principal component analysis (PCA) model, simulation efficiency is very high, based on Kaiser window double spectrum line interpolation FFT harmonic analysis to ensure accurate, is a good helper to learn communication, undergraduate graduation design requirements refer to the standard testing model, uniform linear array of CRB curve.
