线性调频宽带PD制导雷达目标检测研究

摘要

The target detection problem of PD guidance radar is firstly analyzed in clutter regions on the trail-attack and low-altitude condition. Then a novel method is proposed, which utilizes new wideband lincar frequency modulation system to enhance the target detection performance in clutter region. The signal processing and detection performance are discussed thcoretically and calculated for this wideband linear frequency modulation PD seeker radar. The result indicates that the technology of wideband linear frequency modulation can be applied in the PD radar for improving detection performance in the clutter regions significantly.%在分析PD制导雷达在低空尾追情况下杂波区目标检测问题的基础上,提出应用线性调频宽带PD新体制制导雷达,提高杂波区目标检测性能的新方法,并对线性调频宽带PD制导雷达的信号处理流程以及目标检测性能进行了理论分析和计算.结果表明,将宽带线性调频技术应用于PD制导雷达可以显著地改善杂波区目标检测性能,适合弹裁制导场景下的应用.
