中文说明： 部分实现了追踪测速迭代松弛算法，有均匀线阵的CRB曲线，自己编的5种调制信号，借鉴了主成分分析算法（PCA），用于特征降维，特征融合，相关分析等,在MATLAB中求图像纹理特征。
English Description：
Part of the implementation of the tracking velocity iterative relaxation algorithm, there are uniform linear array CRB curve, their own five kinds of modulation signal, using principal component analysis (PCA) algorithm for feature dimensionality reduction, feature fusion, correlation analysis, etc., in MATLAB for image texture features.
