非常适合计算机视觉方面的研究使用,滤波求和方式实现宽带波束形成，通过虚拟阵元进行DOA估计。( Very suitable for the study using computer vision, Filtering summation way broadband beamforming, Conducted through virtual array DOA estimation.)

以二进制显示数据，并将显示内容用文本方式保存以便分析(display data in binary and text content used to analyze ways to preserve)

说明：  里面包含了好几种模式识别的方法，非常的实用，可以直接用在自己的项目中(It contains several pattern recognition methods, very practical, can be directly used in their own projects)

对学习遗传算法的同行有帮助(learning GA peer help!)

运用相关矩阵法，通过计算2 根天线之间的相关系数、多输入多输出(MIMO)的相关矩阵，得到MIMO 信道系数矩阵，在其中加 入智能天线(SA)的导向向量和赋形向量，得到MIMO/SA 矩阵，由此实现对MIMO/SA 多天线空时信道的建模。(Use of the correlation matrix method, the multi-input multi-output (MIMO), correlation matrix, obtained by calculating the correlation coefficient between the two antennas, the MIMO channel coefficient matrix, Smart Antenna (SA) was added in which the guide vectors and shaped vector, obtained MIMO/SA matrix, thus achieving the modeling of the space-time channel, multi-antenna MIMO/SA.)

说明：  S变换在Matlab中对于信号处理方面的应用(S transform in Matlab for signal processing applications)

这是压缩感知领域，一个重构算法--子空间追踪方法，此方法是基于OMP之后的改进算法。(This is a compressed sensing area, a reconstruction algorithm- subspace tracking methods, this method is based on the OMP after the improved algorithm.)

包络分析大多在原始振动加速度信号基础上进行， 受噪声干扰等因素的影响较大 通过对原始振动信号自相关函数作包络分析， 可以有效地抑制噪声， 突出反映故障调制特征(s． Most of the envelope analyses are based on original vibration accelera- tion signal，which is seriously influenced by noise interference． The noise is effectively suppressed by envelop analysis of auto correlation function of original vibration signal，and the modulation characteristics of fault are highlighted．)
