Magnetometer Response of Commonly Found Munitions Items and Munitions Surrogates

Abstract

Target response coefficients for several commonly encountered munitions types and three munitions surrogates were calculated from measurements made using the Naval Research Laboratory Multi-sensor Towed Array Detection System (MTADS) magnetometer array. A best-practice method for making these measurements is presented. Results are presented for four locations in the continental United States: Welcome, MD; Black Hills Army Depot, SD; Hawthorne Army Depot, NV; and a site in Withlacoochee, FL. The minimum-response curves are different for each site because the orientation and strength of the Earth's magnetic field are different at each site. Response curves from Welcome, MD site are shown with corroborative field measurements data overplotted to demonstrate the validity of the method. The results for the large munitions surrogate are the worst fit and this is most likely due to limited ability to degauss large, thick-walled items with available degaussers. Maximum response curves are not presented in this work.
