Abstract

Abstract

End-fire array antenna is extremely suitable for forward-looking or backward-looking blind compensation of airborne radar due to its low wind resistance and high-gain characteristics, while the forward-looking or backward-looking placement of antenna can not avoid the problem of range-dependent clutter. In this paper, in view of the fact that the conventional Space-Time INterpolation Technique(STINT) can not be directly applied to end-fire array clutter compensation in range ambiguity situation, a novel method of end-fire array clutter compensation based on space-time interpolation is proposed based on the characteristics of clutter spectrum for end-fire array airborne radar. The method takes full account of the ambiguous clutter of each range gate and takes the arc corresponding to the main lobe of the long-range stationary clutter ridge as the interpolation reference subspace. Furthermore, it also refines the constrained object of moving target constraints, which achieves effective compensation for the non-stationary clutter of end-fire array in range ambiguity situation. Computer simulation results verify the effectiveness of the proposed method.
