Abstract :
In this contribution we introduce an approach to analyze and detect the formation of Brillouin precursor in a signal propagated through a dispersive vegetation for the frequency band of 2.4GHz. We theoretically predict he evolution and formation of the Brillouin precursor for an ultrawideband waveform: the trapezoidal pulse. The pulse setting allows it to vary between two extreme shapes: rectangular and triangular, by prospering configuring the slope of the trailing and leading edges. We analyze the influence of the pulse setting on the precursor formation.
