摘要
跳频作为现代通信中最主要的一种抗干扰技术手段,在短波、超短波电台军事通信中得到了广泛应用。因此,在智能通信和电子对抗领域,开展对跳频信号的盲参数估计十分重要。随着精确干扰方法的提出,对跳频信号参数估计的要求也愈加精确。因此,针对一类非全驻留跳频信号,通过分析其信号传输机理,给出了全盲参数估计方法。特别是首次提出了针对信号驻留时间的估算方法,为精确干扰提供了前提条件。通过对识别参数与预先设定参数比对,验证了该方法的正确有效性。
Frequency hopping,as one of the most important anti-jamming techniques in modern communication, is widely applied in HF and VHF radio military communication. For this reason, in the field of intelligent communication and electronic warfare, it is very important to implement the blind parameter estimation of frequency hopping signals. With the development of the accurate jamming method, the requirement even more accurate estimation of frequency hopping signal parameter is inevitably required. For a class of nonresident frequency hopping signal, based on analysis of the signal transmission mechanism, the method for full-blind parameters estimation is proposed, especially the method foe estimating the signal residence time, thus to provide a premise condition for accurate interface. The comparison of identification parameters with the preset parameters indicates the validity of the proposed method.
