The method exploits the probablistic sparsity and incorporates prior knowledge of the antenna under test (AUT) to construct an overcomplete representation basis. The performance of the proposed method is analysed as a comparative fashion with Orthogonal Matching Persuit (OMP). date: 2024-04-05 publisher: ELEDIA Research Center - University of Trento referencetext: [1] M.
