Robust space-time interpolation in presence of antenna element error for bistatic airborne radar

We propose robust space-time interpolation method in presence of the antenna element error in this letter. The proposed method adds the correcting space-time steering vectors constraint around the space-time steering vector of the clutter. As a result, the proposed method can mitigate the range dependent problem in presence of the antenna element error in bistatic airborne radar system. The numerical simulation results show the effectiveness of the proposed method.
