ELECTROMAGNETIC IMAGING METHOD BASED ON TIME REVERSAL PROCESSING APPLIED TO THROUGH-THE-WALL TARGET LOCALIZATION

A time reversal method is studied and adapted to throughthe-wall detection and localization of moving targets. Tests are realised on experimental data in a synthetic aperture radar configuration. The efficiency of the method to extract a moving target from a cluttered environment is proved on experimental data.
