A two stage stap algorithm for discrete interference suppression in non-homogeneous environment

摘要

In this paper, a two stage STAP algorithm in non-homogeneous environment is proposed to suppress discrete interference. The training data is pre-processed to eliminate the target component in the first stage. And then rank-reduced STAP algorithm based on sub-matrices is utilized to suppress the discrete interference at a low computational cost as the second stage. The effectiveness of the proposed method has been verified by actual airborne phased radar data.
