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...
In this contribution we introduce an approach to analyze the formation of Brillouin precursor in a signal propagated through a dispersive multilayered medium formed by sea-water and sea-ice. We theoretically predict the evolution and formation of the Brillouin precursor for one classical pulse used: the rectangular one. The design of a ramp pulse based waveform is proposed as near-optimal signal in...
In this contribution we introduce theoretical analysis on the Brillouin precursor formation arising out of a signal propagated through a planar metallic medium for the frequency of 0.1THz. Results have been compared for two different propagated pulses, rectangular and Gaussian. This approach is used to obtain the peak amplitude decay for any kind of transmitted signal travelling through a dispersive...
