Increasingly, commercial off the shelf (COTS) products are finding direct application to DOD needs providing immediate, state-of-the-art technology solutions at a fraction of development contract costs. The terabyte/day data processing requirements of petroleum exploration has led to the development of very fast N-dimensional voxel (3D pixel) rendering software engines. Seismic processing methods also can be directly applied to ground penetrating radar (GPR) data using inverse fft on raw data to produce time verses amplitude and data quality control using signal, noise, waveform, wavefield tools to analyze signal and noise characteristics. Applying 3D seismic reconstruction methods to the 2D ground penetrating radar transects, volumetric (voxel based) models of entire sites (plus or minus 10,000 m2) can be examined quickly. Fused data sets can be simultaneously displayed in voxel space using cross sections, bench cuts, color pallets and variable transparencies to emphasize targets. Applied to the DARPA background clutter data collection experiment, independent data sets simultaneously displayed (fused) in voxel space allow evaluation of target detection and position accuracy of each sensor system (GPR, magnetic/EM, IR). Voxel false color renderings of the fused data can then be used to visually highlight targets co-detection by different sensor systems, helping to eliminate false positives and select the most reliable detection methods. False color voxel renderings from data fusion could lead to rapid unambiguous landmine threat identification for the warfighter.
