Time-frequency distribution(TFD) of multi-component signal can produce cross-components, TFD with fixed kernels perform well only for limited signals.
多分量信号的时频分布会产生交叉项，采用固定核函数的时频分布，其适用的信号形式有很大的局限性。
A certain time window with a fixed width is set and moved along the time axis of a signal.
设置一固定宽度的时间窗，在某一信号上沿时间轴滑动，窗内观察到的信号段被变换到频率域，并在频率域求相关。
