Brancaccio adriana.brancaccio@unina2.it C. Di Dio G. Leone Dipartimento di Ingegneria dell'Informazione – Seconda Universita' di Napoli, Italy The problem of localizing perfectly electrical conducting cylinders of arbitrary radius is dealt with in a two dimensional geometry. A reflection mode multi-frequency multi-bistatic configuration is considered, and a linear inversion algorithm based on the truncated singular values decomposition is proposed. The algorithm is validated against simulated data, and the effect of errors in the knowledge of the cylinders' radius is discussed.
