Abstract:

An ESTCP sponsored demonstration was conducted at the Former Camp Sibert, Alabama, where the objective was to discriminate potentially hazardous 4.2-inch mortars from non-hazardous shrapnel, range, and cultural debris. Six different discrimination techniques were tested and used data from the MTADS magnetometer array, the MTADS time-domain electromagnetic induction array, the MTADS frequency-domain electromagnetic induction array, and a Geonics Limited EM61 commercial cart. Discrimination was achieved using either rule-based or statistical classification of feature vectors extracted from dipole or polarization tensor model fits to detected anomalies. Each of the EM methods used a size-base feature vector and some used shape indicators derived by comparing unconstrained and constrained fit results. Each of the methods successfully discriminated the 4.2-inch mortars from the clutter. The EMI and magnetometer classifications based on size estimates successfully identified all UXO without encountering a single false negative while eliminating over 45 of the native clutter.
