Frequency-Domain Electromagnetic Induction Sensors for the Multi-Sensor Towed Array Detection System

摘要

The Chemistry Division of the Naval Research Laboratory has developed the Multi-sensor Towed Array Detection System for use in unexploded ordnance detection and classification. With support from the Environmental Security Technology Certification Program, we are developing a frequency-domain electromagnetic induction sensor array to extend our capabilities. The first task in this program is to characterize the commercial GEM-3 sensor and assess its suitability for use in a towed array. In this report, we detail our characterization results and note the problems we encountered. We conclude by listing the modifications to the baseline sensors that we will make for the array we will field.
