Under-sea remote sensing using Brillouin precursors

In this contribution we propose a remote sensing technique for subsurface imaging through the seawater. The technique is based on the detection and processing of the evolving Brillouin precursors due to the ultrawideband(UWB) input electromagnetic waves traveling through the dispersive seawater and sand. The proposed technique is validated using simulation studies for layered media, i.e. Seawater and sand.
