常规CFAR检测方法，很有用，可以处理一般雷达回波，得到距离多普勒图(Conventional CFAR detection method is useful)

非线性曲线拟合是已知输入向量xdata和输出向量ydata，并且知道输入与输出的函数关系为ydata=F(x, xdata)，但不知道系数向量x。今进行曲线拟合，求x使得输出的如下最小二乘表达式成立： min Σ(F(x,xdatai)-ydatai)^2(Nonlinear curve fitting is a known input and output vectors xdata vector ydata, and know the relationship between the input and output functions for ydata = F (x, xdata), but do not know the coefficient vector x. As least-squares curve fitting expression today, find x such that the output of the establishment: min Σ (F (x, xdatai)-ydatai) ^ 2)

说明：  matlab中的分数阶工具箱，文件中有两个，一个是的工具箱ninteger，一个是的FOTF(The fractional toolbox in matlab has two files, one is the foreign toolbox ninteger, and the other is the domestic FOTF.)

用MATLAB使信号x(t)产生函数,并显示信号的幅频特性曲线(Using MATLAB to signal x (t) generating function, and displays signal amplitude-frequency characteristic curve)

poisson的PDF&CDF繪圖直接打開檔案RUN即可，生成圖像另有顏色標記(poisson' s PDF & CDF drawing RUN can open the file directly to generate the image and another color marker)

说明：  使用Matlab编写的逆谐波程序。该程序对于不同的参数进行了实验。当图像噪声不同时，选用不同的参数。参数的正确选择很重要。本程序给出了不同噪声比较适合的参数选择(The use of Matlab procedures for the preparation of the inverse harmonic. The program parameters for different experiments. When the image noise is not at the same time, choosing different parameters. Correct choice of parameters is very important. This procedure gives more suitable for different noise parameters)
