Abstract:

We use 2-D forward finite-difference model of the ground-penetrating radar (GPR) to recover ice-wedge depth. The results of the inverse modeling of the synthetic ice-wedge depth showed convergence to the prescribed values. Here we present preliminary results of the synthetic ice-wedge depth recovery using genetic algorithm optimization subroutine. We also applied some noise to the synthetic data and showed up to what level of noise we were able to recover the desired depth. To evaluate the inverse method we calculate the corresponding uncertainties.
