说明：  一种改进的时钟定时抖动估计方法An improved estimation of clock timing jitter(An improved estimation of clock timing jitter)

产生调频步进信号，再进行脉冲压缩，混频，最后进行高分辨率成像。本程序用于测距，参数可以进行修改。注释详细。(stepped LFM generating, and then pulse compression, mixing, and finally high-resolution imaging. The procedure used for ranging, the parameters can be modified. Detailed notes.)

SGP4官方程序,包括matlab，java，C++等源码和说明文件(Official program of SGP4 model,includes Matlab, VC, Java, etc.)

Time vector for the downlink data s where the power vector is a finite state space model.

本程序用c++编了一个提取硬盘物理序列号的dll程序，然后用matlab的m文件调用链接库文件，在matlab语言环境中提取硬盘序列号。本程序中的链接库文件也可用于VC、vb等其他语言调用。(Of this program compiled with c++ the extract the serial number of hard physical the dll procedure, then call matlab m file link library file, extract the hard drive serial number in the the matlab language environment in. Link library files in the program can also be used for the VC, vb and other languages ​ ​ call.)

通过二维图抽象的DCT变换，取前n和系数进行重构得到的图像进行显示(Two-dimensional map by abstraction of DCT, take the first coefficient n and displays the image reconstructed by)

基于小波变换的分开—合并图像分割matlab．采用多尺度小波变换系数作为四分树结构的分开一合并法图像分割的一致性度量 从而在大的图像块中。。去除噪声的影响，在小的图像块中，以小波变换的局部极大值精确定位边缘，根据边缘信息进行分开一合并法图像分割 ．实验表明．算法得到满意的结果 ． (Separately based on wavelet transform- merge image segmentation Matlab. Multi-scale wavelet transform coefficients as the quadtree structure separate consolidation method of image segmentation consistency measure large image block. . To remove the effects of noise, in small image blocks, the local maxima of the wavelet transform precise positioning edge, to separate a combined method for image segmentation according to the edge information. Experiments show. Algorithm to obtain satisfactory results.)

说明：  利用头脑风暴算法，求解cec——2017 benchmark，是史玉回老师的源代码进行的修改(brain storm algorithm)
