基于射频干扰一直是困扰高频雷达尤其是小口径阵列雷达的难题 ,分析了射频干扰的距离 多普勒谱和空间谱的形式 ,提出了一种结合射频干扰检测的运动目标检测方法。应用该方法在没有进行射频干扰抑制时仍能有效地检测出被干扰淹没的目标信号 ,大大提高了高频雷达在射频干扰下目标检测的适应能力

[Abstract]
Radio frequency interference (RFI) is a major problem for operation of HF radar, especially those adopting small antenna array. In this paper, the range-Doppler and spatial spectrum forms of the RFI are analyzed. Basing on which a new method for moving target detection combining the RFI detection is proposed. By the method targets masked by RFI can be effectively detected even with no RFI suppression. The method greatly improved the radar's adaptability for target detection in RFI.
