SAIC Analysis of Survey Data Acquired at Camp Sibert
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.
