Paper Abstract

In this paper, we use an optimized frequency-wavenumber (F- K) migration method to localize subsurface objects form ground penetrating radar (GPR) array dat. F-K migration coherently processes waves collected at different positions by a GPR array by back-propagating the recorded waves to the underground objects, according to the wave equation. Performance of F-K migration on GPR measurement depends on accurate estimation of wave propagation velocity. Due to measurement noise and random ground surface, F-K migration may lose its resolution and accuracy. We propose an optimized method to improve the performance of F-K migration. The optimized method searches for a better velocity estimate in the framework of Tikhonov regularization. The Tikhonov regularization uses minimum entropy as the regularizer. By trying to minimize entropy of F-K migration results, better performance is achieved in terms of resolution and accuracy. Examples from applying the optimized F-K migration on real data are used to demonstrate its performance.
