中文说明：主要是基于mtlab的程序，matlab程序运行时导入数据文件作为输入参数，基于互功率谱的时延估计，BP神经网络用于函数拟合与模式识别，结合PCA的尺度不变特征变换(SIFT)算法，一种流形学习算法（很好用）。
English Description：
Is mainly MTLAB procedures based on, the matlab program is running into data files as input parameters, cross power spectrum time delay estimation based on, the BP neural network for function approximation and pattern recognition, combined with PCA scale invariant feature transform (SIFT) algorithm, a manifold learning algorithm (very good).
