Non-iterative electromagnetic imaging of perfectly conducting screens from limited range far-field data
Résumé
We propose a non-iterative multi-frequency algorithm for the imaging of arbitrarily shaped perfectly conducting screens from limited range far-field data. Based on the factorization of the Multi-Static Response (MSR) matrix collected in the far-field at multiple frequencies in Transverse Magnetic (TM) mode, the imaging problem can be solved through the simple analysis of corresponding eigenvectors. Numerical examples illustrate how the proposed algorithm behaves.
