摘    要:针对常用的非线性时频分析方法不能较好地抑制交叉项干扰的问题,文中提出一种新的跳频信号时频分析方法。将组合时频分布TF方法用于跳频信号分析,提出了跳频信号持续时间、跳变时刻和跳频频率盲提取的改进算法,通过计算机仿真验证了该方法的有效性。

关 键 词:跳频信号  魏格纳分布  组合时频分析

Abstract:A new method for time - frequency analysis of frequency hopping signal is presented, comparing to nonlinear time - frequency analysis of little suppression cross - term interference. The hop timing, hop duration and hop frequencies can be estimated without knowing any a priori knowledge based on TF method. Simulation results demonstrate it is effective and efficient.
Keywords:frequency hopping signal  Wigner- ville distribution  time -frequency analysis
