Application of parametric models to inverse scattering problems

The paper presents a comparative study of two methods of parametric simulation to analyse radar scattering data: the extended Prony method coupled with singular value decomposition (SVD-Prony method) and the direct pencil-of-function (PoF) method. Although this study could be done using a synthesised signal, the authors have preferred to carry out the comparison of both methods when they are applied to the two practical problems of calculating the complex natural frequencies and the scattering centres of radar targets.
