摘要：
To quickly and stably analyze electromagnetic scattering of electrically large bodies of revolution (BORs), compressive sensing is effectively applied to solve sparse matrix equation obtained by wavelet transform. In wavelet domain, only several important rows of sparse impedance matrix were extracted to construct an underdetermined equation by prior knowledge that provided from excitation vectors after wavelet matrix transform. Finally, the unknown current on the surface of BOR is reconstructed by orthogonal matching pursuit. Numerical results of differently shaped BORs were presented to the show the efficiency of the proposed method.
