基于欧几里得距离的聚类分析，主要为数据分析和统计，是一种双隐层反向传播神经网络，是小学期课程设计的题目，有PMUSIC 校正前和校正后的比较，基于互功率谱的时延估计，处理信号的时频分析。- Clustering analysis based on Euclidean distance, Mainly for data analysis and statistics, Is a two hidden layer back propagation neural network, Is the topic of the elementary school stage curriculum design, A relatively before correction and after correction PMUSIC, Based on the time delay estimation of power spectrum, When processing a signal frequency analysis.
