Abstract

It is often desired to widen the interference null width to enhance the robustness of the algorithm in some real anti-jamming environments. A novel space-time adaptive processing algorithm which broadens the null width is proposed in this paper. The proposed method modifies the covariance matrix of wideband jamming based on the analysis of the model of wideband signal and the rotation of the space-time steering vector. When the data mismatch is smaller, the broadening nulling algorithm can effectively suppress interference, which increases the robustness of the algorithm.
