| 摘 要： | 时频分析是分析非平稳信号的一种重要数学分析工具,魏格纳分布是时频信号分析的非线形变换。针对跳频信号的特点,本文提出了一种采用平滑伪魏格纳(SPWVD)时频分析来分析跳频信号的方法,该方法可以在不需要知道信号任何先验参数的情况下,估计出跳频信号的跳频频率、跳变时刻等参数。

| Abstract: | Time-frequency analysis is an important mathematics analyze tool in analyzing non-placidity signal, Wigner-Ville distribution is the non-linear transform of time-frequency analysis. A method for estimating the parameters of unknown frequency-hopping signals based on Smoothed Pseudo WVD is proposed. Using this method, the parameter of signals such as hopping frequencies and hop timing could be estimated without knowing any priori knowledge. |

| Keywords: | frequency-hopping hop timing Wigner-Ville distribution |
