Down-looking ground penetrating radar (DLGPR) has been used extensively for landmine detection. Most operational prototype systems and data collection devices use multiple transmit and receive antennas that are directed downward and mounted at the front or bottom of a moving platform. The resultant 3D datasets generated by these devices have commonalities that lend themselves to systematic analysis. While in-air measurements allow for GPR antenna characterization, it has been difficult to compare the effectiveness of a specific GPR antenna configuration as applied to the landmine detection problem. We have developed software and analysis techniques to bridge the gaps in understanding that exist between GPR antenna characterization and assessment of DLGPR landmine detection systems. We examine several datasets that were collected over an identical set of buried landmines by different DLGPR systems, and compare the mine signatures by using a simple measure of effectiveness. The simplicity of the metric allows one to separate the effects of the system from the algorithms designed to enhance mine detection performance.
