基于空时内插的机载双基地雷达杂波抑制方法
Clutter Suppression Algorithm for Bistatic Airborne Radar Based on the Space Time Interpolation Transformation
摘要
Abstract
This paper focuses on the problem of nonhomogeneous clutter suppression of bistatic airborne radar. Firstly, the conventional space time adaptive processing ( STAP) algorithms are discussed for the suppression of the nonhomogeneous clutter in bistatic airborne radar. Secondly, based on the analysis of previous methods, an effective STAP algorithm based on the improved space time interpolation transformation (ImSTINT) is presented. The clutter subspace of training sample in the bistatic airborne radar can be projected to the clutter subspace monostatic radar via the proposed algorithm, and the degrees of freedom of clutter subspace is decreased greatly after the transformation. The performance of the proposed algorithm is more perfect robust than conventional STAP algorithm, and has a lower requirement of training data.关键词
