"Time Reversal (TR) technique is applied to localize an UWB source inside a building or buried under rubble produced by disasters. The reversed field is calculated by the FDTD-TR method applying as boundary conditions the field measured, but reversed in time, at some observation points located on the boundary. A refinement of the estimated position of the UWB emitter is carried out by a novel method based on delay time. Illustrative numerical examples are finally given."

Abstract

"Time Reversal (TR) technique is applied to localize an UWB source inside a building or buried under rubble produced by disasters. The reversed field is calculated by the FDTD-TR method applying as boundary conditions the field measured, but reversed in time, at some observation points located on the boundary. A refinement of the estimated position of the UWB emitter is carried out by a novel method based on delay time. Illustrative numerical examples are finally given."
