“…In the marine environment, the surface topography generally restricts the sensor standoff to ∼1-2 m above the seafloor which is largely equivalent to airborne sensor deployment [101]. As the sensor to UXO standoff increases, interpretation of the data can become more difficult and sensitivity becomes a major concern where often small ordnance items are below the detection threshold of the best magnetometer.…”

There is universal agreement between the United Nations and governments from the richest to the poorest nations that humanity faces unprecedented global challenges relating to sustainable energy, clean water, low-emission transportation, coping with climate change and natural disasters, and reclaiming use of land. We have invited researchers from a range of eclectic research areas to provide a Roadmap of how superconducting technologies could address these major challenges confronting humanity.Superconductivity has, over the century since its discovery by Kamerlingh Onnes in 1911, promised to provide solutions to many challenges. So far, most superconducting technologies are esoteric systems that are used in laboratories and hospitals. Large science projects have long appreciated the ability of superconductivity to efficiently create high magnetic fields that are otherwise very costly to achieve with ordinary materials. The most successful applications outside of large science are high-field magnets for magnetic resonance imaging, laboratory

“…One such SERDP-funded project by Gamey et al [101] developed a full-tensor gradiometer using an array of high-temperature SQUID vector magnetometers as shown in figure 23. This low-noise system produced good results stationary, however it was plagued with noise issues once the transition was made to a moving platform.…”

“…An aeromagnetic gradient tensor system based on hightemperature SQUID was used for underwater unexploded ordnance detection (Keenan et al, 2011). Gamey (2008) proposed the aeromagnetic gradient tensor system which is using eight SQUID devices to measure nine components of the tensor matrix. With regard to fluxgate magnetic tensor gradiometers, a right-angled tetrahedral tensor system based on four fluxgate sensors was proposed by Bracken et al (2005), but this system has large structure errors.…”

Purpose The differential magnetic gradient tensor system is usually constructed from the three-axis magnetic sensor array. While the effects of measurement error, sensor performance and baseline distance on localization performance of such systems have been widely reported, the research about the effect of spatial design of sensor array is less presented. This paper aims to provide a spatial design method of sensor array and corresponding optimization strategy to localization based on magnetic tensor gradient to get the optimum design of the sensor array. Based on the results of simulation, magnetic localization systems constructed from the proposed array and the traditional array have been built to carry out a localization experiment. The results of experiment have verified the effectiveness of magnetic localization based on the proposed array. Design/methodology/approach The authors focus on the localization of the magnetic target based on magnetic gradient by using three-axis magnetic sensor array and combine a design method with corresponding optimization strategy to get the optimum design of the sensor array. Findings This paper provides an array design and optimization method for magnetic target localization based on magnetic gradient to improve the localization performance. Originality/value In this paper, the authors focus on the magnetic localization based on magnetic gradient by using three-axis magnetic sensors and study the effect of the spatial design of sensor array on localization performance.
