摘要

摘要: 该文论述了利用新近研制的小型化多通道外辐射源雷达系统，开展基于长期演进(LTE)信号的外辐射源雷达目标探测实验研究的情况。首先从实测信号的模糊函数出发，探讨了该信号作为第三方照射源的优势。然后介绍了该体制雷达的系统方案设计以及外场实验。最后给出了不同目标的典型探测结果，从实验上证实了利用LTE信号实现地面及低空目标探测的技术可行性，为该探测技术的发展奠定了基础。

Abstract: This article presents experimental results of target detection using a miniaturized multichannel passive radar system that exploits Long Term Evolution (LTE) signals. First, the advantages of LTE signals are discussed with respect to their ambiguity function. Second, both system design and field experiments are introduced. Finally, agreements between different targets and their truth obtained in the results prove the technical feasibility of using LTE signals for detecting ground and low-altitude targets via field experiments, thus forming the basis for further development of LTE-based passive radar.
