 The decomposition of the time reversal operator (D.O.R.T.) method allows detection and localization of point-like scatterers through a very simple and robust process. Here, with the aim of applying this method to the detection and the localization of buried objects, we focus on the influence of the restriction of the measurements to a line of receivers. The finite size of the objects is also taken into account, as well as losses in the embedding medium. A simple behavior of the time reversal operator is exhibited, almost independent of the polarization, which permits one to detect scatterers in the resonance domain, with very low ambiguity. Experimental data obtained in an anechoïc chamber confirm our theoretical predictions.
