说明：  这是关于LFM信号利用WHT变换估计其参数的仿真代码。程序基于时频分析包，但对其中相应部分做了修改。程序中有算法的详细设计内容。
(This is on the LFM signal using WHT transform to estimate the parameters of the simulation code. Procedures based on time-frequency analysis package, but part of which had been amended accordingly. Procedures in the detailed design of the contents of algorithm.)
