  A fast parameter estimation method of SinFM signal is proposed. The method consists of two parts:using time-frequency ridge extraction to get the curve of the frequency law,then applying random Hough transformation of sinusoidal curve to the time-frequency plane.

  本文提出了一种正弦调频信号参数估计的快速算法.首先对信号进行时频分析,通过时频脊提取的方法得到正弦调频信号的频率变化曲线,然后在时频图上进行正弦曲线的随机Hough变换检测,从而得到正弦调频信号的参数估计。
