摘要

摘要: 在小孔径高频地波超视距雷达系统中，普遍存在一种覆盖一定距离单元，多普勒单元以及全部角度单元的电离层杂波。为抑制该杂波并且提高被其淹没目标的检测概率，该文提出一种基于空间多波束的电离层杂波抑制算法。该方法充分利用宽波束时波束间具有很强相关性的特点，以及实际情况下杂波覆盖的距离单元数或多普勒单元数远远多于目标所覆盖的单元数的特点来实现杂波信息的估计与抑制。仿真实验与实测数据结果均证明该方法可以有效地抑制电离层杂波，并显著地提高被淹没目标的检测概率。

Abstract: In the small-aperture high-frequency surface-wave over-the-horizon radar system, the ionospheric clutter that covers a certain range bins, the Doppler bins and all the angle bins is generally existent. To restrain the clutter and ensure the submerged target easy detect, this paper presents an ionospheric clutter suppression algorithm based on spatial multi-beam. This method makes full use of the characteristics of the strong correlation between the beams in the wide beam and the characteristics of the number of range bins or Doppler bins covered by the clutter is far more than the number of bins covered by the target to achieve the clutter information estimation and suppression. The results of the simulation experiment and the measured data show that the method can effectively suppress the ionospheric clutter, and significantly improve the detection probability of the submerged target.
