  1. UXO Classification with MetalMapperTMData D.D. “Skip” Snyder - Snyder Geoscience, Inc. Co-Authors: Mark Prouty, David George, Mary Poulton, Anna Szidarovszky, Tom King Partners in Environmental Technology Conference & Workshop, December 2009

  2. Outline • Background • Interpretation • Data Processing • Classification (Decisions) • SLO Results • Summary Remarks

  3. Background MetalMapper

  4. MetalMapper – Design features • Compact, man-portable electronics • 3 Orthogonal Tx Loops • 7 tri-axial induction (dB/dt) receiver cubes • Mapping/Static Acquisition Modes

  5. SLO – Cued ID Deployment (SLO)

  6. MetalMapper Receivers 10 cm Cubes 3 Component, Orthogoal Multiturn Receiver Coils

  7. Transmitter Waveform

  8. MetalMapper Static Survey 2494 pts Occupied 2178 Target Picks 5 NEW Target Picks 309 Repeats Survey Time – 6.5 Days 56.6 hr Production Rate 383 pts/day 42 pts/hr

  9. Interpretation Data Processing

  10. Interpretation – Parameter Extraction

  11. Interpretation Discrimination & Classification

  12. Interpretation - Classification

  13. 4 Polarizability Types - SLO

  14. Classification Results

  15. Test ROC Curves - SLO MetalMapper – SLO List 1 MetalMapper – SLO List 2

  16. Future Develop More Compact MetalMapper System Lighter Weight, Less Transmitter Coils Additional TEM Systems? Deeper TEM System for Mineral Exploration Metal Detection System for Deeper Targets
