Abstract:

Leveraging the lessons learned in ESTCP MR-201610 and with the extensive fielding of the BTGGapEOD UltraTEM Marine family of systems in Europe, the objective of this project is to integrate a high power, AGC-grade electromagnetic induction EMI sensor array in the marine towed array MTA platform to provide dynamic UXO classification at standoff distances compatible with the MTAs maneuvering profile through the water. This report documents the results of our design and testing of the proposed EMI transmitter and transmitter loop designs and physical testing of test articles to confirm the proposed transmitter design will meet the requirements for successful classification performance.
