The Ground Penetrating Radar (GPR) has potential to characterize soils both vertically and horizontally. The effectiveness of using GPR relies on the interpretation of soil targets in the radargrams. For identifying the targets in their correct depths, a velocity model of the terrain is required. However, a velocity model cannot be directly obtained from GPR models using a monostatic antenna. An alternative is the generation of a depth model by measuring the velocity of the electromagnetic pulse from hyperbolas created in the radargram from the interaction of the pulse with point scatterers. On the other hand, the radargram does not always present these point scatterers for the estimation of the pulse velocity and generation of an accurate depth model.... |
