A new poles extraction technique is presented based on modified damping least squares algorithm combined with matrix pencil method. Initial values of poles are obtained using matrix pencil method to overcome local convergence of nonlinear least squares. Stability of iterative algorithm is improved utilizing modified damping least squares algorithm instead of other methods. Perfect simulation results from conducting sphere show that the new technique is applicable for extraction poles of conducting targets and is a promising method compared with others methods.
