Deconvolução da Assinatura da Fonte de Dados de Radar de Penetração em Solo

Fernando A. Neves, Mark S. Roulston, John A. Miller


Data from a ground penetrating radar (GPR) survey conducted at a site near
Cambridge, IJ.K., were procéssed. The application.of source signature
deconvolutión using complex spectral division has significantly increased the
resolution of the subsurfàce radar data. The source wavelet was statistically
estimated from the radargrams. A velocity structure is suggested, supported by
borehole data and analysis of a common mid-point (CMP) gather. A subsurface
profile of the area from a 600 m long transect was constructed. _This profile
showed a clearly defined water table and a gentle rise in an underlying clay
layer across the transect.
