摘要
提出了一种基于谱图的时频分析算法来对单个JTIDS信号实施有效检测。首先分析了JTIDS信号特点,其次建立了单个JTIDS信号模型,然后通过算法分析和实验仿真,对JTIDS信号的跳周期和跳频频率进行有效估计,从而达到检测JTIDS信号的目的。
A algorithms based on spectrum of time-frequency analysis for effective detection of single JTIDS signal is provided. The first analysis of the JTIDS signal characteristics, secondly, estabhshing the single JTIDS signal model, then effectively estimating JTIDS signal Hop-Duration and frequency hopping through algorithm analysis and experimental simulation,so as to achieve the purpose of detection of JTIDS signals.
