Synthetic Aperture Radar (SAR) Raw Signal Simulation

matlab时频分析配套源码第3章的程序，请大家共享(Matlab time-frequency analysis supporting source Chapter 3, please share)

通过MATLAB对一幅多个人物的图像进行，人脸轮廓的提取，识别。效果不错，譬如毕业照这样的照片能有很好的结果。(By MATLAB to more than one person in the image , extract facial contour recognition . Good results, such as this photo graduation photo can have a good result .)

利用OMP算法重构二维图像，简单易懂，便于初学者学习。(Two-dimensional image reconstruction algorithm using OMP, easy to understand.)

通用Matlab实现Dijkstra最短路算法(General Matlab achieve Dijkstra shortest path algorithm)

64QAM基带系统接收机matlab代码：添加AWGN噪声，进行接收端匹配滤波器，8倍下采样，解调信号。(64QAM baseband system receiver matlab code: add AWGN noise, matched filter receiving end, eight times the down-sampling, the demodulated signal.)

This scheme is also called DPSK since MZ modulator provides the “digital” phase modulation if it is biased at null instead of quadrature. No coherent detection is needed if data is differentially pre-coded.

先生成这样的一幅500*500的RGB彩色图像：一个田字格，左上和右下是绿色，右上是红色，坐下是蓝色。并进行如下处理：（a）将该图像转换到HSI空间，用25*25的平均模板模糊H分量图像，再转换回RGB空间；（b）重复（a），只是这次处理的是S分量。最后简单分析结果。（内含实验报告） (Mr. into a 500* 500 RGB color image: a field word lattice, the upper left and lower right is green, the upper right is red the sit is blue. And be handled as follows: (a) the image into the HSI space, fuzzy H 25* 25 average template component image, and then converted back to RGB space (b) Repeat (a), only this time to deal with the S component . Finally, a simple analysis of the results. (Contains experimental report))
