Comparison between Matrix Pencil and Prony methods applied on noisy antenna responses

A comparison between the TLS-Prony and the TLS-Matrix Pencil methods applied on antenna backscattered responses in presence of noise is presented. This work focuses on errors on the poles extracted when the SNR of the signal becomes low. Algorithms of the two methods are quickly described. The two algorithms are applied on the backscattered responses of a dipole and an UWB antenna. The TLS-Matrix Pencil method is less sensitive to noise and especially for damping coefficient extraction.
