Abstract

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.
