Satellite Interference Localization Based on Compressive Sensing Theory
摘要
Abstract
The conventional direction finding methods have poor performance in the actual application. A satellite interference localization method based on the compressive sensing( CS) theory is proposed. Based on the interference signal angle’s sparseness in angle space,the corresponding direction of arrival( DOA) model,and the over-complete dictionary of atoms and measuring matrix by randomly sampling unit vector are constructed. Combined with the source estimation technology,the estimation using orthogonal matching pursuit( OMP) algorithm is obtained. The simulation results show that the method can estimate simultane-ously the coherent signal amplitude and bearing and is suitable for the rapidly moving interference targets. It has smaller computational load and better engineering usability. Research in this paper promotes the ap-plication of compressive sensing in satellite interference localization.关键词
