Munitions Classification Library Update and Expansion Blossom Point Data Collection Report

Abstract : Advanced geophysical classification data were collected for 66 example munitions at the Blossom Point test facility using three sensors: the Modified Portable Decoupled Electromagnetic Induction Sensor (MPEDEMIS), the Time-domain Electromagnetic Multi-sensor Towed Array Detection System (TEMTADS) 2x2, and the MetalMapper. These data were inverted to determine primary axis polarizabilities for the example munitions. The inversion results were converted to Hierarchical Data Format version 5 (HDF5) and Geosoft Oasis Montaj formats to be used as libraries for future advanced geophysical classification projects. The process and requirements for data acquisition were documented in an attached standard operating procedure (SOP) to facilitate library additions by other technology users.
