Abstract One of the tough task that airborne bistatic radar faced is the extensive existing non-stationary of bistatic clutter which will degrades the performance of STAP remarkably. A novel bistatic modified technique named Improved joint Space-Time INterpolation Technique (ImSTINT) is introduced in this paper. Compared with traditional space-time interpolation techniques, ImSTINT minimizes the degrees of freedom of subspace clutter after transformation to the utter most, and thus eliminates the influence of non-stationary of clutter on clutter suppression in airborne bistatic radar system. Furthermore, ImSTINT has faster convergence rate and better suppression performance against mainlobe clutter.
