摘要
本文提出了一种基于功率谱估计的跳频信号检测的新方法,该方法主要是利用定频信号、跳频信号的功率谱随时间变化的差异性,通过对定频信号功率谱进行对消以实现跳频信号的检测,分析了影响定频信号功率谱对消的因素,计算机仿真结果证实了该方法的有效性。
a new method for frequency-hopping signals detection based on power spectral estimation is proposed in this paper, using the difference of the power spectral between the frequency-fixed signals and frequency-hopping signals along with the time variety for suppressing the frequency-fixed signals and detecting the frequency-hopping signals. The factors affecting the suppression of the frequency-fixed signals power spectral are analyzed. The computer simulation results are also testified to show the validity of this method.
