Integration of micro-fabricated atomic magnetometers on military systems
2016
A new generation of ultra-high sensitivity magnetic sensors based on innovative micro-electromechanical systems
(MEMS) are being developed and incorporated into military systems. Specifically, we are currently working to fully
integrate the latest generation of MicroFabricated Atomic Magnetometers (MFAMs) developed by Geometrics on
defense mobility systems such as unmanned systems, military vehicles and handheld units. Recent reductions in size,
weight, and power of these sensors has enabled new deployment opportunities for improved sensitivity to targets of
interest, but has also introduced new challenges associated with noise mitigation, mission configuration planning, and
data processing. Our work is focused on overcoming the practical aspects of integrating these sensors with various
military platforms. Implications associated with utilizing these combined sensor systems in working environments are
addressed in order to optimize signal-to-noise ratios, detection probabilities, and false alarm mitigation. Specifically, we
present collaborative work that bridges the gap between commercial specialists and operation platform integration
organizations including magnetic signature characterization and mitigation as well as the development of simulation
tools that consider a wide array of sensor, environmental, platform, and mission-level parameters. We discuss unique
deployment concepts for explosive hazard target geolocation, and data processing. Applications include configurations
for undersea and underground threat detection - particularly those associated with stationary or mobile explosives and
compact metallic targets such as munitions, subsea threats, and other hazardous objects. We show the potential of
current and future features of miniaturized magnetic sensors including very high magnetic field sensitivities, bandwidth
selectivity, and array processing.
