matlab中仿真韦布尔分布杂波的幅度函数以及功率谱分布，并使用plot函数做出理论和实际图形对比(matlab simulation Weibull clutter in amplitude function and the power spectral distribution, and use the plot function to make a comparison of theoretical and practical graphic)

matlab绘制三维Hilbert谱程序，保证可用。上传文件采用的是.txt形式，实际使用时只需要将后缀改为.m即可在matlab中运行。(matlab draw three-dimensional Hilbert spectrum procedures to ensure that available. Upload file uses a .txt form, the actual use of the suffix to .m only need to be run in matlab.)

matlab数值计算代码，MATLAB开发人员编写，推荐(matlab numerical code, written in MATLAB developers recommend)

径向基函数是一个取值仅仅依赖于离原点距离的实值函数，也就是Φ（x）=Φ(‖x‖),或者还可以是到任意一点c的距离，c点称为中心点，也就是 Φ（x，c）=Φ(‖x-c‖)。任意一个满足Φ（x）=Φ(‖x‖)特性的函数Φ都叫做径向量函数，标准的一般使用欧氏距离，尽管其他距离函数也是可以的。一些径向函数代表性的用到近似给定的函数，这种近似可以被解释成一个简单的神经网络，径向基函数在支持向量机中也被用做核函数。(Radial basis function depends only on the value of a real-valued function of the distance from the origin, i.e. Φ (x) = Φ (x ‖ ‖) or may also be the distance to any point c, c is called the center point , i.e. Φ (x, c) = Φ (xc ‖ ‖). Satisfy any one of Φ (x) = Φ (x ‖ ‖) characteristic functions are called radial vector function Φ standard Euclidean distance is generally used, although other distance functions are also possible. Some typical uses radial function approximation given function, this approximation can be interpreted as a simple neural network, RBF in support vector machines have also been used to make nuclear functions.)

This code consist of various filters and their comparison, The performance metrics are determined using PSNR value, SSIM value.

做速度分析和动校正很有用,大家可以试一试，大家赞一个谢谢(it is for velocity analysis and NMO， and it is very useful，thank you)
