Two dimensional DOA estimation method for superimposed coherent multipath using $\ell$1-norm regularized minimization is evaluated. First, the matrix for searching DOA is generated by modevectors belonging to any specific directional range. Next, a central DOA of superimposed modevectors is evaluated with the matrix. And each DOA of paths is estimated by using $\ell$1-norm regularized minimization with the matrix. As an alternative SAGE method is compared. In conclusion, the minimization method is advantageous for needless of the path number and initial DOAs as prior informations for processing. |
