| 摘 要： | 杂波非均匀是双基地机载雷达杂波抑制面临的一大难题，直接制约着常规STAP方法的杂波抑制性能。该文提出了一种改进的联合空时内插方法(ImSTINT)。相对于传统的联合空时内插方法，ImSTINT方法映射变换后的子空间杂波自由度更小，因此能够彻底消除非均匀杂波对双基地机载雷达杂波抑制性能的影响。此外，该方法具有更快的收敛速度和更好的主杂波抑制性能。

| 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. |
