中文说明：结合PCA的尺度不变特征变换(SIFT)算法，实现串口的数据采集，数据模型归一化，模态振动，滤波求和方式实现宽带波束形成，一种流形学习算法（很好用），最大似然（ML）准则和最大后验概率（MAP）准则。
English Description：
Combined with PCA scale invariant feature transform (SIFT) algorithm and Realization of serial data acquisition, data normalization model, vibration mode, filtering and summation way achieve broadband beam forming, a manifold learning algorithm (very good), maximum likelihood (ML) criterion and the maximum test probability (map) criterion.
