基于稀疏重建的信号DOA估计
Direction-of-Arrival estimation based on sparse signal reconstruction
摘要
Abstract
This paper proposes a modified Direction of Arrival(DOA)estimation method based on Minimum Redundancy Linear Array(MRLA)from the sparse signal reconstruction perspective. According to the structure feature of MRLA that obtaining larger antenna aperture through a smaller number of array sensors, MRLA is combined with ℓ1-SVD method to estimate signal DOAs. Simulations demonstrate that the proposed method is effective, and compared with ℓ1-SVD meth-od it can estimate more DOAs of signal source, and it is capable of estimating more DOAs with fewer antenna elements.关键词
