%*********************WVD函数***************************
% 使用说明：
% 输入变量X表示是信号数据（列向量）；
% fft_number是做FFT使用的离散频率点数，可以用来决定频率采样的精度。
% 生成的wvd数据，行表示时间，列表示频率：即每个时刻的fft放在列中

%************ WVD_Hough变换 ***************
%使用说明:
% wvd为要做Hough变换的wvd矩阵;
% M为斜率采样点数;
% N为频率轴截距采样点数,一般取值范围为频率轴一个周期(m/2);
% 得到的Hough变换的'截距'轴的对应值为初始频率;'斜率'轴的K值
% 对应的实际斜率
