移动窗口二维相关光谱方法matlab的实现，完全是自己参照公式编的哦。。移动窗口二维相关光谱是一种新的二维相关分析方法,它将移动窗口的概念和二维相关分析方法有效地结合在了一起,利用移动窗口将庞大的光谱数据按矩阵分割成若干个便于操作的子矩阵,用二维相关光谱分别处理,将得到的结果综合分析,用以光谱变量和扰动变量为坐标的等高图表现出来,从中可以非常直观地观察出光谱强度在扰动变量方向上的变化,进而找出引起光谱强度突变的特征扰动点。(Moving window two-dimensional correlation spectroscopy method matlab realization, is entirely their own formulas reference the Oh. . Moving window two-dimensional correlation spectroscopy is a new two-dimensional correlation analysis method, it will move the window concept and two-dimensional correlation analysis method is effective to combine together, using the moving window at the huge spectral data matrix is ​ ​ divided into a number of easy to operate a sub-matrix, respectively, using two-dimensional correlation spectroscopy process, comprehensive analysis of the results obtained for the spectral variables, and disturbance variables manifested contour map coordinates, which can visually observe the spectral intensity of the direction of the disturbance variable The change, then find mutations characteristic spectral intensity caused disturbance point.)

线性调频（LFM）脉冲压缩雷达仿真,脉冲压缩雷达能同时提高雷达的作用距离和距离分辨率。这种体制采用宽脉冲发射以提高发射的平均功率，保证足够大的作用距离；而接受时采用相应的脉冲压缩算法获得窄脉冲，以提高距离分辨率，较好的解决雷达作用距离与距离分辨率之间的矛盾。(Linear frequency modulation (LFM) pulse compression radar simulation, pulse compression radar while increasing the role of the radar range and range resolution. This system uses the width pulse emission in order to improve the average power emitted, to ensure a sufficiently large effective distance accepted when the corresponding pulse compression algorithm to obtain a narrower pulse, in order to improve the distance resolution, the better solution of the radar range and range resolution the contradiction between the rate.)
