瑞利分布＋杂波雷达信号MATLAB仿真程序源码，希望望对有做雷达信号的朋友有帮助 可直接使用。 已通过测试。 (Rayleigh distribution+ hybrid radar signal MATLAB simulation program source code, I hope to look on the friend of a radar signal to help can be used directly. Has been tested.)

这为一个通过频域重构方法获得ＳＡＲ信号点目标的ＭＡＴＬＡＢ仿真软件，是微波成像雷达领域的一个极好的软件(This is a reconstruction obtained by frequency domain SAR signal point target MATLAB simulation software, is the field of microwave imaging radar, an excellent software)

常用指令工作空间管理管理指令和函数搜索路径的管理(指令窗控制 运算符和特殊算符(Management of common commands workspace management management instructions and functions of the search path (command window control operators and special operators)

In this code, the BER performance of a system which uses sparse channel estimation is compared with a system which uses LSE channel estimation. It is shown that using sparse technique improves the performance of the system

用matlab语言编写的试井分析的程序，做出了均质无限大地层的图像(Matlab language with well test analysis procedures, has made an infinite homogeneous strata image)

说明：  正弦信号，单个频率的正弦信号，频率为1KHz，幅度为5(Sinusoidal signal, a single frequency sinusoidal signal, a frequency of 1KHz, the range of 5)

谐波小波程序变参数的积分程序多点人工生成地震波程序低通滤波程序经验模式分解降噪程序(Harmonic Wavelet programmed parameters points integration process of artificial seismic waves to generate low-pass filtering process procedures empirical mode decomposition noise reduction procedure)

Monochromatic (gray scale) low resolution image is converged to colored image by false color mapping to "hot" color scheme. This RGB image is then converted to Hue, Saturation and Value (HSV) image. Value component is replaced by higher resolution image and the resulting HSV image is converted back to RGB. This RGB merged image converted to gray scale is a merged image with improved spatial resolution.

matlab实现svm，能很好的实现相关反馈(matlab to achieve svm, relevance feedback can be good)
