NICOP - Environmental Magnetic Noise Reduction
Abstract
Technical Approach and Justification ONR Code 321 is funding FASORtronics LLC in collaboration with the University of Arizona to demonstrate the ability to measure high-altitude magnetic fields using ground-based laser-excitation of Sodium ions in the ionosphere (contract N00014-14-C-0110).1 The aim of the project is to determine if the magnetic field variations measured at high-altitude can be used for geomagnetic noise cancellation in airborne magnetic anomaly detection (MAD) systems. FASORtronics has extensive experience in making laser guide star measurements, but Mr. Nelson has much more expertise at real-time time and frequency-domain methods for airborne Magnetic Anomaly Detection (MAD) noise reduction. 2 He will assist FASORtronics with the design of the experiment, and conduct most of the correlation analysis to determine if the technique is feasible for geomagnetic noise reduction. NSWC-Carderock Ft. Lauderdale Division is leading a defense/academia group to instrument the South Florida Ocean Measurement Facility (SFOMF) with a variety of undersea and on-shore sensors (contract N6554014D0008 ). The aim is to determine if the electromagnetic fields generated in the ocean3 and in the air above the ocean, can be correlated with measurements of the oceanographic parameters (water flow, salinity, temperature, etc.). ONR is supporting the project by funding NRL Stennis to assist with the definition of instrumentation requirements. Mr. Nelson has been involved in the experimental design and data analysis of several previous oceanographic electromagnetic field measurement trials.4-6 His expertise at magnetic field modeling and data processing will greatly enhance the core signal processing capabilities of the defense/academic group. This NICOP proposal only addresses the initial work to identify the sensors, plan the sensor laydown, and analyze the initial data for quality assurance. A follow-on NICOP proposal may be submitted for the detailed analyses of subsequent data sets with matching funds from SFOMF.
