Paper Abstract

Ground penetrating radar (GPR) is used in explosive hazard clearance. Handheld sensors are utilized by operators during search and localization sweeps. These two styles of ground interrogation follow a standard operating procedure (SOP) that attempts to maximize both ground coverage and rate of advance (ROA). As a result, the data collected is non-uniformly sampled, with areas of missing data. We analyze a number of data interpolation methods in order to develop discrimination algorithms and human visualizations. We analyze the performance of interpolative methods for sweep patterns in the parallel and perpendicular direction by using Mean Squared Error (MSE), Mean Absolute Error (MAE), and Structural Similarity Index (SSIM). Overall, a nearest neighbors (2-NN) method performs best.
