Abstract: 
In this study, we provide a detailed analysis of the frequency division duplex long term evolution downlink (FDD LTE DL) signal for passive bistatic radars that use the signal as an illuminator of opportunity. In particular, we analyze the cross-ambiguity function and illustrate its undesired deterministic peaks in the Doppler dimension due to the specific structure of the FDD LTE DL signal. A new adaptive mismatched filtering method is proposed for pre-processing the original reference signal to suppress these undesired deterministic peaks in the range-Doppler processing. The effectiveness of our proposed method is demonstrated via simulations following robustness analysis, showing that all undesired peaks are suppressed below −40 dB, with only 1.7 dB reduction in the main peak.

摘要:本文详细介绍了LTE频分物理下行链路信号(LTE信号)作为照射源的外辐射雷达系统。根据LTE信号特定的物理帧结构分析其模糊函数特性,同时探讨多普勒维不同类型副峰的形成机理。提出一种基于自适应参考信号预处理的失配滤波方法求解模糊权值因子,抑制模糊副峰的影响,提高目标检测性能。仿真结果表明所提方法可将副峰抑制至−40 dB以下,同时主峰损失仅为1.7 dB,验证了所提算法有效性。
