Abstract
Sensors incorporating Superconducting Quantum Interference Devices (SQUIDs) provide the greatest sensitivity for magnetic anomaly detection available with current technology, The Coastal Systems Station (CSS) has pioneered the use of superconducting magnetic sensors in the field operating onboard airborne and undersea moving platforms, where environmental and instrument noises present operational problems which are not encountered under laboratory conditions. Basic conceptual approaches for utilizing these sensors onboard moving platforms, including field deployable sensor configurations, are described. Environmental and instrumental technical issues are also addressed. A historical sketch of sensor development, current sensor capabilities, recent technology advances, and future trends is included. Naval applications and dual use opportunities for this technology are given based on experience developed at CSS.
