摘要
为了对截获的跳频信号进行有效分析并估计其参数,根据跳频信号频率随时间变化的特点,提出了一种基于局域波分析的跳频参数估计方法。理论分析和仿真结果表明,这种新的时频分析方法能够有效抑制噪声干扰,得到跳频信号的时频图效果很好,是一种有效的跳频信号参数估计方法。
To effectively analysis the intercepted frequency hopping（FH） signal and estimate its parameters, according to the characteristics of the FH signal frequency changes over time, a FH parameter estimation method based on local wave analysis is proposed in this paper. Theoretical analysis and simulation results show that this new time - frequency analysis method can effectively suppress noise. The effect of time - frequency figure of FH signal is very good. Therefore, it is a kind of effective method of parameter estimation of FH signal.
