把hdf数据读入execl，是图形界面，用matlab2010开发，打开hdfchuli.m文件即可执行。(Hdf data read into execl, graphical interface, matlab2010 development, open hdfchuli.m file can be executed.)

说明：  产生一个chirp信号，给出时域及频域特性。利用匹配滤波器进行滤波。如果有延时也能正确滤波。(Generate a chirp signal, given the time domain and frequency domain characteristics. Filtering using matched filter. If there is delay filter can correct.)

数据降维算法 K_L变换是一种最优正交变换，以矢量信号X的协方差矩阵Ф的归一化正交特征矢量q所构成的正交矩阵Q，来对该矢量信号X做正交变换Y=QX，则称此变换为K-L变换（K-LT或KLT）。(Data reduction algorithm K_L optimal orthogonal transform is a transformation to vector signal covariance matrix Ф X normalized orthogonal feature vector composed of q orthogonal matrix Q, to be orthogonal to the vector signal X transformation Y = QX, called the KL transform transform (K-LT or KLT).)
