Method and apparatus for detecting subsurface targets using data inversion and a temporal transmission line model

CCDC ARL

A method and apparatus for detects one or more subsurface targets by receiving a reflectivity data from two or more subsurface reflectors using a ground penetrating radar. The two or more subsurface reflectors may include the one or more subsurface targets and a medium surrounding the one or more subsurface targets. An impedance data for the two or more subsurface reflectors is calculated by inverting the reflectivity data using a temporal transmission line model with a “layer-peeling” method. One or more constitutive parameters of the two or more subsurface reflectors are calculated based on the impedance data. The one or more subsurface targets are detected based on a change in the one or more constitutive parameters.
