Analysing the Possibility of Detecting Underground Tunnels using Forward and Inverse Modeling of Ground Penetrating Radar (GPR) Data
Abstract:   (653 Views)
Studying the possibility of detecting buried structures like underground tunnels is one of the most important and difficult problems in the field of passive defence. Among common and traditional geophysical methods, the ground penetrating radar (GPR) technique has the highest resolution so that it can be used to detect varieties of subsurface heterogeneities and buried targets located near the Earth’s surface. In this research, by using forward and inverse modeling, the ability of GPR method is examined to detect underground tunnels through a case study. For this purpose, simulated models in the shape of horizontal cylinder are investigated using two-dimensional finite difference modeling in ReflexW software. Also, the effects of diameter, depth, and overburden parameteres of the tunnels on detecting subsurface tunnels using GPR method have been analysed.
Keywords: ground-penetrating radar (GPR) - Forward modeling -inverse modeling - subsurface tunnels - passive defense
