Root-OPM: a new linear subspace algorithm applied to thin pavement thickness estimation by GPR

Résumé

In this paper, we propose a new linear subspace algorithm, called root-OPM, for Time Delay Estimation (TDE)of backscattered radar signals. The proposed algorithm corresponds to the polynomial version of the OPM method. In comparison with OPM, root-OPM allows to improve resolution power, a better noise robustness and a lower computational load. Furthermore, root-OPM enables to afford the same performance as for rootMUSIC at medium SNR and beyond.
