Paper Abstract

A database of vehicle mounted GPR mine data acquired over rough road conditions is analyzed to determine the sensitivity to random and rapid variations in antenna heights due to naturally occurring antenna bounce. Results are also described for data acquired during tests designed to induce specific bounce profiles during data collections. Significant increases are observed in false alarms, and significant decreases are observed in mine detection probabilities at rougher test lane locations. Perhaps the most significant antenna height factor was discovered to be rapid and large GPR amplitude changes due to the variations in antenna height and thus propagation loss. Finally, normalization techniques developed by AARD are examined to correct for these GPR antenna bounce factors and are shown to be effective in most cases, particularly for some of the more severe induced bounce scenarios.
