Echo generation by SVO

We deal with an approach, based on the Singular Value Optimization (SVO) technique, for the synthesis of array-based generators of near-field echoes. The approach selects the grid wherein enforcing the design specifications and the radiator locations to control the ill-conditioning associated to the determination of the array excitation coefficients. Following the SVO optimization, the array coefficients are determined by a Singular Value Decomposition (SVD).Numerical results are provided for the synthesis of the near-field scattered by a perfectly conducting sphere illuminated by an elementary dipole.
