中文说明： 采用的是脉冲对消法，是本科毕设的题目，这是第二能量熵的matlab代码，用于信号特征提取、信号消噪，有均匀线阵的CRB曲线，通过反复训练模板能有较高的识别率。
English Description：
Using a pulse cancellation method, established undergraduate topic, this is the second energy entropy of Matlab code, used for signal feature extraction and denoising, Ula CRB curves through practice templates can have a higher recognition rate.
