摘要 通过自相关算法可以比较准确地进行周期估计,并采用基于Wigner-Ville时频分布(WVD)峰值估计方法,在信噪比较高的情况下,估计了单分量LFM信号的载频和调制斜率。 With self-corrective arithmetic, the period of LFM can be estimated and with the WignerVille(WVD) time-frequency distribution peak estimation, the carry frequency and modulation slope of the single LFM is estimated at high S/N.
