| 摘 要： | 跳频信号作为扩频通信的一种，由于其具有较强的抗干扰，抗截获的能力，并能作到频谱资源共享，因此在军事应用中得到了广泛的应用。文章针对通信对抗中的跳频信号盲检测问题，提出了一种基于循环平稳特性的跳频信号盲检测算法。该算法将渐进最优x^2检验方法推广到跳频信号的检测问题上，提出检测统计量，从而完成对高斯白噪声环境下的跳频信号检测。实验结果表明，与传统能量检测方法相比，该算法对于高斯白噪声环境中的跳频信号具有更好的检测性能，且计算量小，易于实现。

| Abstract: | As one of spread spectrum communication,frequency-hopping signals has been widely used in military applications because of its strong anti-interference,anti-interception and spectrum sharing.The paper proposes a blind detection algorithm of frequency-hopping signals based on cyclostationarity about blind detection of frequency-hopping signals in communication countermeasures.The algorithm extends the asymptotically optimal chi-squared test to frequency-hopping signals detection,and proposes test statistics,... |
